(in case you don't know, * means multiply and / means divide)
Answer:
There is no solution to the equation.
Step-by-step explanation:
In order to solve the system by substitution, we need to solve the second equation for x.
x - 2y = -8
x = 2y - 8
Now that we have that, we can put that in for x in the other equation and solve for y.
3x - 6y = -12
3(2y - 8) - 6y = -12
6y - 16 - 6y = -12
-16 = -12
No solution
Answer:
-x+2
Step-by-step explanation:
3x+(2−4x)
=3x+2-4x
=3x-4x+2
=-x+2
