Y= 3x - 10
y= 2x - 5

Answers

Answer 1
Answer:

The solution to the system of equations is x = 5 and y = 5. The coordinates (5, 5) represent the point where the two lines intersect in the xy-plane, and it is the unique solution to this system of linear equations.

Given that the system of equations:

y = 3x - 10                                     (1)

y = 2x - 5                                       (2)  

Since both equations are set equal to y, equate the right-hand sides of the equations since they represent the same value of y:

3x - 10 = 2x - 5

Now, let's solve for x:

3x - 2x = -5 + 10

x = 5

Now, found the value of x, substitute it back into either of the original equations to find the corresponding value of y.

Let's use the equation (1):

y = 3x - 10

y = 3(5) - 10

y = 15 - 10

y = 5

Hence, the values of x and y are 5 and 5. The system of equations have unique solution.

Solve the system of equations for x and y:

y= 3x - 10\ny= 2x - 5

Answer 2
Answer:


If you're looking for a solution for both equations and had a choice between the 3 ways of solving it, I would choose substitution for this problem. So..

2x-5=3x-10

Move like terms to their own sides.

Take 2x away from both sides, and add 10 to both sides. That should leave you with

5=x

Now that you have the x, plug it into the equation that works best for you to solve.

That should be y=2(5)-5

y=10-5

y=5

(5,5) is your solution.

Solve the following equation:
​ 12(b+2)+3b=−1

​Enter your answer as a fraction.

Answers

The solution to the equation 12(b+2) + 3b = -1 is b = -5/3.

What is the solution to the given equation?

Given the equation in the question:

12( b + 2 ) + 3b = -1

To solve the equation 12( b + 2 ) + 3b = -1, first apply the distributive property.

Distribute the 12 across the terms inside the parentheses:

12( b + 2 ) + 3b = -1

12×b + 12×2 + 3b = -1

Simplifying, we get:

12b + 24 + 3b = -1

Collect and combine the like terms on the left side of the equation:

12b + 3b + 24 = -1

15b + 24 = -1

Subtract 24 from both sides of the equation:

15b + 24 - 24 = -1 - 24

15b = -1 - 24

15b = -25

Divide both sides by 15:

b = -25/15

Simplify

b = -5/3

Therefore, the value of b is -5/3.

Answer: -5/3

Step-by-step explanation:

12(b + 2) + 3b = -1

12b + 24 + 3b = -1

15b + 24 = -1

15b = -1-24

b = -25/15 = -5/3

Answer:

(-2,8)

Step-by-step explanation:

3x+3y = 18

2x+y = 4

Multiply the second equation by -3

-3(2x+y) = -3*4

-6x-3y = -12

Add this to the first equation

3x+3y = 18

-6x-3y = -12

-------------------------

-3x = 6

Divide each side by -3

-3x/-3 = 6/-3

x = -2

Now solve for y

2x+y = 4

2(-2) +y = 4

-4+y =4

Add 4 to each side

-4+4+y = 4+4

y =8

Answer:

(-2,8)

Step-by-step explanation:

3x + 3y = 18 (1)

2x + y = 4 (2)

(1) - 3(2)

3x + 3y = 18

-(6x + 3y = 12)

-3x = 6

x = -2

Using (2)

2(-2) + y = 4

-4 + y = 4

y = 8
