5x+15=2x
Consider the first equation. Use the distributive property to multiply 5 by x+3.
5x+15-2x=0
Subtract 2x from both sides.
3x+15=0
Combine 5x and -2x to get 3x.
3x=-15
Subtract 15 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-15}{3}
Divide both sides by 3.
x=-5
Divide -15 by 3 to get -5.
x=-5 y=0 z=0
The system is now solved.
