First multiply out the bracket

5x - 30 =4x + 4

Then subtract 4x from each side

x - 30 = 4

then add 30 to each side

x = 34

5x-30=4x+4+(30)
+30
5x=4x+34
-4x -4x
*x=34*

5(x - 6) = 4x + 4
5*x - 5*6 = 4x + 4
5x - 30 = 4x + 4
5x - 4x = 30 + 4
x = 34

you have to use the distributive property.


5(x-6)=4x+4

multiply 5 by everything in parentheses

5x-30=4x+4

then you subtract or add to get like terms on the same side.

5x-30=4x+4
-4x
1x-30=4
+30
1x=34

then divide by 1 so you can get x by itself and thats your answer.

1x=34
x=34
