Need help with problem can you help 5x+3y=22 y=2x

Answers

if y = 2x, let's replace it on $5x+3y=22$

$5x+3*(2x)=22$

$5x+6x=22$

$11x=22$

$\boxed{\boxed{x=2}}$

Therefore

$y=2x$

$y=2*2$

$\boxed{\boxed{y=4}}$

5x+3y=22 y=2x
5x+3(2x)=22
5x+6x=22
11x=22
x=2

y=2(2)
y=4
x=2 y=4

I'm afraid that this is a weak attempt at your math teachers trying to teach you variables. Pretend that each shape is the letter x. Let's solve the first one together. 2x-1=5. To find what x=, you need to work backwards. Instead of subtracting one, add one. 5+1 is 6. Now you have 2x=6. Since x is being multiplied by 2, you need to divide 6 by 2. 6/2 is 3. x=3.
For the next one, we know that the triangle, or x, is 3. Again, let's make a different letter for the square. Let's make the square be y. Now your problem is 3 + y = 1. Once again, let's reverse our thinking to solve for what y=. 1-3 is -2. y=-2. See how that works? Now we need to Solve for the last one. The triangle, which we named x and is 3, and the square, which we named y and is -2, can be plugged into the final equation. 3-2(-2)=z. -2 * -2 is 4, and 3 + 4 is 7. Your final answer is 7.

PLEASE Find the equation of the line............................perpendicular to the line y= 5x -1 and passes through the points (10,8)

Answers

Since it's perpendicular to the line with the slope 5, you take the reciprocal of 5 which is 1/5 and change the sign: -1/5. So you have the equation: y=-(1/5)+b. To find b you substitute x and y for the coordinate (10,8).
y=(-1/5)x+b
8=(-1/5)10+b
8=(-10/5)+b
8=-2+b
+2 +2
10=b

So your new equation is: y=1x+10
