2(3x + 5y = 322)
6x+10y=966
3x-10y=8
Canceled out the positive 10y and the negative 10y. Subtract the rest and you will receive the answer for x.
2x= 958
/2 =/2
X= 479
Solve for y. I’m going to use the first equation to find y.
3x+5y=322
3x+5(479)=322
3x+2,395=322
-2,395=-2,395
3x= -2073
/3 = /3
X= -691
2(-6x+10y=-8)
-12x+20y=-16
7x-20y= 1
Canceled out the positive 10y and the negative 10y. Subtract the rest and you will receive the answer for x.
-19x=-17
/-19 = -19
X=0.89
Solve for y. I’m going to use the first equation to find y.
7x-20y= 1
7(0.89)-20y= 1
6.23-20y=1
-6.23 = -6.23
-20y = -5.23
/-20= /-20
y= -0.2651
