Solve for 4(3x-1)+8=2(3x+5)-8

Butoxors [25]

Answer:

x = -1/3

Step-by-step explanation:

4(3x-1)+8=2(3x+5)-8

Distribute

12x -4 +8 = 6x +10 -8

Combine like terms

12x +4 = 6x +2

Subtract 6x from each side

12x-6x +4 = 6x-6x +2

6x+4 =2

Subtract 4 from each side

6x+4-4=2-4

6x =-2

Divide each side by 6

6x/6 = -2/6

x = -1/3
