Answer:
If you need the equation: 10x - 12
If you need the equation more simplified: x - 1.2
Explanation:
(2x + 7) - (8x + 5)
Move the parts of the equation around
(2x + 8x) - (7 + 5)
Add 2x and 8x together
10x - (7 + 5)
Add 7 and 5 together
10x - 12
If you need it even more simplified, continue
10x - 12
Divide by 10
x - 12/10
Simplify
x - 1.2
