3x+15+11x-5/2=47
14x+10/2=47
7x+5=47
7x=42
x=6
1. Multiply both sides by 4x-1

2.Simplify

3.Multiply both sides by 7
4x-1=3x7
4.Simplify 3*7 to 21
4x-1=21
5. Add one to both sides
4x=21+1
6. Simplify 21+1 to 22
4x=22
7.Divide both sides by 4
x=
8.Simplify

Multiply the equation 2x + y = 1 by 3 to obtain same coefficients of y.

Substract the equation 3x + 3y = 15 from 6x + 3y = 3 to eliminate the terms of y.

Substitute -4 for x in the equation 2x + y = 1 to obtain the value of y.

So solution of equations is (-4,9).
