Answer:
In this equation x is equal to h + 1
Step-by-step explanation:
To solve this, follow the order of operations for solving equations.
(6x-4h) = 10 + 4(1.5 + 0.5x) ----> Distribute the 4
(6x - 4h) = 10 - 6 + 2x ----> Simplify
6x - 4h = 4 + 2x ----> Subtract 4 from both sides
6x - 4h - 4 = 2x ----->Subtract 6x from both sides
-4h - 4 = -4x ----> Divide by -4
h + 1 = x
The answer is 6
