Question

Solve 4(2x - 1) - 3 = 9(x - 4). (4 points)

-29
32
13
29

Answer 1

You need to first distribute what's in the parentheses.
4 times 2x and 4 time -1
9 times x and 9 times -4
then you'll have 8x - 4 - 3 = 9x - 36
consolidate like terms (subtract -3 from -4)
Then you need to get x by itself by subtracting 8x from both sides
-7 = x - 36
to further isolate it add 36 to both sides
29 = x
And there you go.
