QuestionSolve 12x7=18-\frac{1}{2} x - 7 = 18 for xx. What is the value of xx?

Studdy Solution

STEP 1

Assumptions1. The equation is 1x7=18-\frac{1}{} x -7 =18 . We are solving for xx

STEP 2

First, we isolate the term with xx by adding 77 to both sides of the equation.
12x7+7=18+7-\frac{1}{2} x -7 +7 =18 +7

STEP 3

implify the equation.
12x=18+7-\frac{1}{2} x =18 +7

STEP 4

Calculate the value on the right side of the equation.
12x=25-\frac{1}{2} x =25

STEP 5

To solve for xx, we need to get rid of the 12-\frac{1}{2} coefficient. We can do this by multiplying both sides of the equation by 2-2.
2×12x=2×25-2 \times -\frac{1}{2} x = -2 \times25

STEP 6

implify the equation.
x=2×25x = -2 \times25

STEP 7

Calculate the value of xx.
x=50x = -50The solution to the equation 12x7=18-\frac{1}{2} x -7 =18 is x=50x = -50.
