First step: combine the x terms, x - 4x = -3x.
Second step: Add 32 to both sides, which will cancel out the -32.
Now you have -3x = 32.
To solve for x, divide 32 by -3. The answer is -10.667.

➷ Simply substitute the values into the equations to see if it's correct:
Since the time taken will be more than 2 hours, we can try it with the value 3
t(x) = 70 + 5(3) = 85
g(x) = 30 + 15(3) = 75
As you can see, this is the incorrect choice as when a value more than 2 hours is used, the second engineer has a cheaper cost.
