Answer:
x=5
Step-by-step 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
