Answer:
x = 12.25
Step-by-step explanation:
Given
x - 3(x - 7) = 4(x - 7) - 2x ← distribute parenthesis on both sides
x - 3x + 21 = 4x - 28 - 2x ← simplify both sides
- 2x + 21 = 2x - 28 ( subtract 2x from both sides )
- 4x + 21 = - 28 ( subtract 21 from both sides )
- 4x = - 49 ( divide both sides by - 4 )
x = [tex]\frac{49}{4}[/tex] = 12.25
Answer: x=12.25
Step-by-step explanation: First, multiply the numbers into the parentheses. You will get:
X -3x +21 = 4x -28 -2x
Combine like terms.
-2x +21 =2x -28
Isolate x by adding 2x to each side.
21 =4x -28
Add 28 to each side to get x by itself.
49=4x
Divide by 4.
X =12.25
