6x+15=4-x
Use the distributive property to multiply 3 by 2x+5.
6x+15+x=4
Add x to both sides.
7x+15=4
Combine 6x and x to get 7x.
7x=4-15
Subtract 15 from both sides.
7x=-11
Subtract 15 from 4 to get -11.
x=\frac{-11}{7}
Divide both sides by 7.
x=-\frac{11}{7}
Fraction \frac{-11}{7} can be rewritten as -\frac{11}{7} by extracting the negative sign.
