Answer :
Put equation two into the first equation by replacing values of y with 2x-4
4(2x-4)+3x=12
8x-16+3x=12
11x=28
x=28/11
Put the value of x into the original equation to find the value of y.
y=2(28/11)-4
y=56/11-4
y=12/11
x=28/11 and y=12/11
4(2x-4)+3x=12
8x-16+3x=12
11x=28
x=28/11
Put the value of x into the original equation to find the value of y.
y=2(28/11)-4
y=56/11-4
y=12/11
x=28/11 and y=12/11
