4(x-3)-6x=-24
To solve for x, you must first get rid of the parentheses. Use the distributive property. Distribute the 4 to all parts of the binomial inside.
4(x-3)-6x=-24
4x-12-6x=-24
Combine like properties.
-2x-12=-24
Now use simple algebra to complete the rest. Add 12 to both sides.
-2x=-12
Divide by -2.
x=6
