Question

7 + x = 4(x - 2) I need each step as well as the properties used in each

Answer 1

x=5

Explanation:

Step 1: Simplify both sides of the equation.

7+x=4(x−2)

7+x=(4)(x)+(4)(−2)(Distribute)

7+x=4x+−8

x+7=4x−8

Step 2: Subtract 4x from both sides.

x+7−4x=4x−8−4x

−3x+7=−8

Step 3: Subtract 7 from both sides.

−3x+7−7=−8−7

−3x=−15

Step 4: Divide both sides by -3.

−3x

−3

=

−15

−3

x=5
