Answer:
y=3
x=2
Step-by-step explanation:
Making substitution
y+7=5x
y=5x-7
Substituting the y into the other equation
-3x-2(5x-7)=-12
-3x-10x+14=-12
-13x=-14-12
-13x=-26
x=2
We have x=2 then substitute it into the first equation
y+7=5(2)
y+7=10
y=10-7
y=3
So the answer is
y=3
x=2
Answer:
x=2 and y=3
Step-by-step explanation:
After solving, you can check your work by substituting the values of x and y into the equations and solving for them.
3+7=10
10=10
-6-6= -12
-12 = -12
