3a + 2 - 5a = -14. Can someone solve this for me.
Answers
Answer:
a=8
Step-by-step explanation:
3a + 2 - 5a = -14
Combine like terms
-2a +2 = -14
Subtract 2 from each side
-2a +2-2 = -14-2
-2a = -16
Divide each side by -2
-2a/-2 = -16/-2
a = 8
Answer:
a = 8
Step-by-step explanation:
-2a + 2 = -14
-2a = -16
-16/-2 = 8
a = 8

Given equation: 5 - 8|-2x| = -75
Step 1: Remove the absolute value by considering two cases:
Case 1: -2x is positive
Case 2: -2x is negative
Step 2: Solve for Case 1 (when -2x is positive):
5 - 8(-2x) = -75
5 + 16x = -75
16x = -75 - 5
16x = -80
x = -80 / 16
x = -5
Step 3: Solve for Case 2 (when -2x is negative):
5 - 8(2x) = -75
5 - 16x = -75
-16x = -75 - 5
-16x = -80
x = -80 / -16
x = 5
So, the solutions for the equation are x = -5 and x = 5.
You can verify these solutions by substituting them back into the original equation to make sure they satisfy the equation.
Answer:
No solution
Step-by-step explanation:
To solve the equation 5-8|-2x|=-75, we can follow these steps:
Step 1: Isolate the Absolute Value
We begin by isolating the absolute value term by adding 8|-2x| to bothsides of the equation:
- 5-8|-2x|+8|-2x|=-75+8|-2x|
Simplifying the left side, we get:
- 5=-75+|-16x|
Subtracting 5 from both sides, we get:
- |-16x|=-80
Step 2: Remove the Absolute Value
Since the absolute value of a number is always positive, we can split the equation into two cases:
- -16x=80 or -16x=-80
Step 3: Solve for x
Solving for x in the first case, we get:
- -16x=80
- x=-5
Solving for x in the second case, we get:
- -16x=-80
- x=5
Step 4: Check the Solution
We need to check if the solutions we found satisfy the original equation. Plugging in x=-5, we get:
- 5-8|-2(-5)|=-75
- 5-8|10|=-75
- 5-80=-75 (which is false)
Therefore, x=-5 is not a solution.
Plugging in x=5, we get:
- 5-8|-2(5)|=-75
- 5-8|(-10)|=-75
- 5+80=-75 (which is false)
Therefore, x=5 is also not a solution.

Answer with explanation:
⇒49=7×7 =1 × 49
Factors of 49 = 1,7,49
⇒It is given that ,98 is a Multiple of 49.
98 = 49 × 2
So, apart from factors of 49, number 2, and 98 are also included in the set of factors of 98.
→Factors of 98 are =1,2,7,49,98
Since 98 is a multiple of 49, 98 must have more factors than 49.

If two lines have the same slope and different intercepts, then they will never cross each other; they are parallel lines. Therefore, they have no solutions since a solution is where the lines cross.
