Question

Given the linear relationship,
y = 3.75x + 48, determine x if y = 74.25

Answer 1

The answer to this question is 7

Answer 2

x = 7

Explanation:

74.25=3.75x+48

Step 1: Flip the equation.

3.75x+48=74.25

Step 2: Subtract 48 from both sides.

3.75x+48−48=74.25−48

3.75x=26.25

Step 3: Divide both sides by 3.75.

3.75x /3.75 = 26.25 /3.75

so x = 7
