Answer:
3x - 4 = 8 - x
Rearrange the terms
3x - 4 = -x + 8
add four to both sides of the equation
3x - 4 = -x + 8
3x - 4 + 4 = -x + 8 + 4
Add the numbers
3x = -x + 12
subtract x from both sides of the equation
3x = -x + 12
3x + x = -x + 12 + x
combine the terms
4x = 12
x = 4 / 12 = 3
x = 3
Hope it helps you
Good morning have a great day ahead
Happy Valentine's Day ❤❤
