+219 3(4x-1)-7x=17
First expand 3(4x-1)-7x
3(4x-1)-7x
distribute the 3 into the parenthasis
12x - 3 - 7x
Then combine like terms so 12x - 7x = 5x
5x - 3 = 17
Now add 3 on both sides
5x - 3 + 3 = 17 + 3
5x = 20
Divide 5 on both sides
5x/5 = 20/5
x = 4
Hope this helps ;P

+194 Simplifying
3(4x + -1) + -7x = 17
Reorder the terms:
3(-1 + 4x) + -7x = 17 (-1 * 3 + 4x * 3) + -7x = 17 (-3 + 12x) + -7x = 17
Combine like terms:
12x + -7x = 5x -3 + 5x = 17
Solving
-3 + 5x = 17
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right. Add '3' to each side of the equation.
-3 + 3 + 5x = 17 + 3
Combine like terms:
-3 + 3 = 0 0 + 5x = 17 + 3 5x = 17 + 3
Combine like terms:
17 + 3 = 20 5x = 20
Divide each side by '5'. x = 4 Simplifying x = 4
