In the systems of equation below, I can eliminate x by adding because the coefficients are opposites.
4x + 8y = 20
−4x + 2y = −30
True
False
What variable do you eliminate, and what do you multiply the equation(s) by?
5x + y = 9
10x − 7y = −18
You eliminate x, and divide the bottom equation by 2
You eliminate x, and multiply the top equation by 2
You eliminate y, and multiply the top equation by 7
You eliminate y, and multiply the top equation by -7
Does the system have one, none or infinite solutions?
8x + 4y = 12
y = -2x + 3
one solution, (0,3)
one solution, (3,0)
No solution(parallel lines)
