answer for y-3x=-30 x+2y=94
This is a two-step equation and I am trying to find the value of x and y.
I don't see this being solved in only two steps.
y - 3x = -30
x + 2y = 94
Solve the first equation for y in terms of x.
y - 3x = -30
y = 3x - 30
Substitute that into the second equation.
x + 2y = 94
x + 2(3x - 30) = 94
x + 6x - 60 = 94
7x = 94 + 60 = 154
x = 154 / 7 = 22
Now, we can solve for y.
y - 3x = -30
y - 3(22) = -30
y - 66 = -30
y = -30 + 66
y = 36
Verify that with the second equation.
x + 2y = 94
22 + 2(36) = 94
22 + 72 = 94
94 = 94
x = 22; y = 36
