Equate any two equations to get
one equation.
4x + 2y = x - 3y + 1
3x + 5y = 1 ..........(i)
x - 3y + 1 = 2x + y + 13
-x - 4y = 12 ...... (ii)
Solve equations (i) and (ii) i.e
Multiply eqn (ii) by -3
3x + 5y = 1
3x + 12y = -36
-7y = 37;
y = - $\frac{37}{7}$
From (ii) x + 4(-$\frac{37}{7}$)
From (ii) x = 4(-$\frac{37}{7}$) = -12
x - $\frac{148}{7}$ = -12
x = $\frac{64}{7}$
