Solve the equation by substitution.
x+6y=-2, -3-18y=6
AAAaannndd the bot gets it wrong yet again!
x+6y=-2, -3-18y=6
The 2nd equation gives
-18y = 9
y = -1/2
so x = 1
I suspect you may have meant
x+6y=-2
-3x-18y=6
But that reduces to
x+6y = -2
x+3y = -2
y = -(x+2)/6
so it has no unique solution.
First, solve for y in the first equation:
y = -1/6x - 1/3
Substitute this value for y in the second equation:
-3 - 18(-1/6x - 1/3) = 6
Simplify:
-3 - 3x - 6 = 6
Solve for x:
3x = 9
x = 3
Substitute x = 3 into the first equation to solve for y:
3 + 6y = -2
6y = -5
y = -5/6
