2x+14+5x=3x+3
Use the distributive property to multiply 2 by x+7.
7x+14=3x+3
Combine 2x and 5x to get 7x.
7x+14-3x=3
Subtract 3x from both sides.
4x+14=3
Combine 7x and -3x to get 4x.
4x=3-14
Subtract 14 from both sides.
4x=-11
Subtract 14 from 3 to get -11.
x=\frac{-11}{4}
Divide both sides by 4.
x=-\frac{11}{4}
Fraction \frac{-11}{4} can be rewritten as -\frac{11}{4} by extracting the negative sign.
