Question

X over 3 plus 15 equal 42 what is x

Answer 1

Answer: X=81

Explanation:

• The equation can be written as x/3+15=42 to help better understand it.
• Step 1: Simplify both sides of the equation.

1/3x+15=42

• Step 2: Subtract 15 from both sides. 1/3x+15=42

-15 -15 1/3x=27

• Step 3: Multiply both sides by 3

3*(1/3x)=(3)*(27) X=81

• We are left with X=81 we are going to leave the equation alone now since we can't do anything else with it. To make sure we did the math correct were going to plug in 81 for x and see if we get 42 for the value.
• 81/3+15=?42

42=42 True

• Therefore the answer is 81.
