Simplify brackets
6 - 3x - 10 + 4(2 - x) = 15
Simplify 6 - 3x - 10 + 2(2 - x) to -4 - 3x + 4(2 - x)
-4 - 3x 4(2 - x) = 15
Expand
-4 - 3x + 8 - 4x = 15
Simplify -4 - 3x + 8 - 4x - 7x
4 - 7x = 15
Subtract 4 from both sides
-7x = 15 - 4
Simplify 15 - 4 to 11
-7x = 11
Divide both sides by -7
[tex]x = -\frac{11}{7}[/tex]
