Question

Solve the following systems by substitution. Substitute the expression in the second equation into the first equation and solve. (If the system has no solution, enter NONE for each answer.)

x-y=-8
y=2x+12

anonymous · Answer

Input y=2x+12 into the x-y=-8
That equals x-2x-12=-8
Solve for x

anonymous · Answer

Once you solve for x, input x into one of the equations to solve for y

anonymous · Answer

Do you get it or do you want me to solve it?

anonymous · Answer

i dont understand where you got the -12 from

anonymous · Answer

Well y is negative in x-y=-8 so you have to multiply 2x+12 by -1

anonymous · Answer

so think of it like x-(2x+12)=-8

anonymous · Answer

got it?
