Answer
x=2
y=7
Work Step by Step
y = 3x +1
4y - 8x = 12
Substitute y = 3x + 1 to the second equation.
4 ( 3x + 1 ) - 8x = 12
12x + 4 - 8x = 12 ( use the distributive property )
4x +4 =12 ( simplify)
4x +4 - 4 = 12 - 4
4x =8 (divide both sides by 4 )
x=2
Substitude x = 2 to the first equation.
y= 3 $\times2$ + 1
y=6+1
y=7
