Question

Turn the equation {425 = 320 + x} into an equation. Show the work.

a) x = 105
b) x = 85
c) x = 120
d) x = 95

Answer 1

To solve for x in the equation {425 = 320 + x}, we subtract 320 from both sides, yielding x = 105. Thus, the correct answer is (a) x = 105.

Step-by-step explanation:

To turn the equation {425 = 320 + x} into an equation solving for x, we need to isolate x on one side of the equation. We can do this by subtracting 320 from both sides of the equation:

425 = 320 + x
-320 -320 (subtracting 320 from both sides)

This results in:

425 - 320 = x

Now, we perform the subtraction:

105 = x

Therefore, the value of x is 105, which corresponds to option (a) x = 105.
