Answer:
(-3, 0)
Step-by-step explanation:
We can solve this algebraically (substitution or elimination) or graphically.
Step 1: Multiply the first equation by -2
-4x - 12y = 12
4x - 3y = -12
Step 2: Add the 2 equations together and solve for y
-15y = 0
y = 0
Step 3: Plug y back into an original equation to get x
2x + 6(0) = -6
2x = -6
x = -3
And we have your answer!
Answer:
2x+6y=-6 ........1
4x-3y=-12 ........2
Simplify equation 1
2x + 6y = -6
Divide both sides by 2
You will get
x + 3y = -3
Make x the subject
x = - 3 - 3y
Substitute x into equation 2
4x - 3y = - 12
4(- 3 - 3y) - 3y = - 12
-12 + 12y - 3y = -12
9y = -12 + 12
9y = 0
Divide both sides by 9
y = 0
Substitute y = 0 into x = - 3 - 3y
You will get
x = - 3 - 3(0)
x = -3
Therefore x = - 3 and y = 0
Hope this helps
