4x-4-\left(x+3\right)=0
Use the distributive property to multiply 4 by x-1.
4x-4-x-3=0
To find the opposite of x+3, find the opposite of each term.
3x-4-3=0
Combine 4x and -x to get 3x.
3x-7=0
Subtract 3 from -4 to get -7.
3x=7
Add 7 to both sides. Anything plus zero gives itself.
x=\frac{7}{3}
Divide both sides by 3.
