If 2x-4(3-x)=18, then x=_____? Can someone please help me with this problem
denis-greek [22]

Answer:

Answer is below

Step-by-step explanation:

Simplify both sides of the equation.

2x-4(3-x)=18\\2x+(-4)(3)+(-4)(-x)=18

DIstribute

2x+-12+4x=18\\(2x+4x)+(-12)=18

CLT

6x+-12=18\\6x-12=18

Add 12 to both sides.

6x-12+12=18+12\\6x=30

Divide both sides by 6.

\frac{6x}{6} =\frac{30}{6}\\ x=5
