3x+3=4\left(x-1\right)
Use the distributive property to multiply 3 by x+1.
3x+3=4x-4
Use the distributive property to multiply 4 by x-1.
3x+3-4x=-4
Subtract 4x from both sides.
-x+3=-4
Combine 3x and -4x to get -x.
-x=-4-3
Subtract 3 from both sides.
-x=-7
Subtract 3 from -4 to get -7.
x=7
Multiply both sides by -1.
