Question

Solve the systems

y=4x+12 and y=-2x+6

Answers:
A: 0,3
B: -1.8
C: 12,6
D: no solution
E: infinitely many solutions

Answer 1

Because both equal y we can combine them to get:
4x + 12 = -2x + 6

Answer 2

Thn you add 2x to both sides to get rid of it on the right side so now we have:
6x + 12 = 6

Answer 3

Now we want to isolate 6x, so subtract 12 from both sides to get:
6x = -6

Answer 4

Then divide both sides by 6 to get:
x = -1

Answer 5

Ah okay thank you
