Question

Given 425=320+x, solve for x.
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 need to isolate x on one side of the equation.

We start by subtracting 320 from both sides of the equation: 425 - 320 = 320 + x - 320. This simplifies to 105 = x.

Therefore, the value of x is 105.

Step-by-step explanation:

To solve the equation 425 = 320 + x for x, we need to isolate x on one side of the equals sign. We do this by subtracting 320 from both sides of the equation:

• 425 - 320 = 320 + x - 320
• 105 = x

Therefore, the solution to the equation is x = 105, which corresponds to option (a).
