Answer:
1/5
Step-by-step explanation:
In order to solve this, you need to simplify. In this case, we would need to distribute first.
-5x - (-7 - 4x) = -2(3x - 4)
-5x + 7 + 4x = -6x + 8
Combine like terms:
-5x + 6x + 4x = 8 - 7
-x + 6x = 1
5x = 1
X needs to be by itself, so you would divide by 5 (the coefficient in front x) on both sides. So,
x = 1/5
4
3x+5=17
3x=17-5
3x=12
x=12/3
x=4
ok sooo
2x - 5 + - x - 2
hopefully it makes sense and is visible
