5x-3\left(x-1\right)=0
Consider the first equation. Multiply both sides of the equation by 15, the least common multiple of 3,5.
5x-3x+3=0
Use the distributive property to multiply -3 by x-1.
2x+3=0
Combine 5x and -3x to get 2x.
2x=-3
Subtract 3 from both sides. Anything subtracted from zero gives its negation.
x=-\frac{3}{2}
Divide both sides by 2.
x=-\frac{3}{2} y=6 z=6 a=6
The system is now solved.
