2(x - 7) = 4
2x - 14 = 4
2x - 14 + 14 = 4 + 14
2x = 18
2x / 2 = 18 / 2
x = 18 / 2
x = 9

First is to distribute/multiply 2 to x-7 giving you an answer of 2x - 14 = 4.
Then transpose -14 to the other side(Remember when transposing use the opposite sign so in this case from negative to positive) so 2x = 14 + 4 giving you a total answer of 2x = 18 then divide 18 by 2 giving you the answer of x.
x = 18/2 making x = 9.
Step by Step Solution:
2(x-7) = 4
2x - 14 = 4
2x = 14 + 4
2x = 18
x = 18/2
x = 9

2(x-7)=4
2x-14=4 first multiply the part in the parentheses by 2
+14 +14 Then add 14 to each side to get x isolated
2x = 18 Then divide both sides by 2 to see the value of x
x=9

2(x - 7) = 4
2(x) - 2(7) = 4
2x - 14 = 4
2x = 4+14
2x = 18
x = 18/2
x = 9
