Q:
# Solve the system of equation?2x - 4y = 107x - y = 12

Accepted Solution

A:

Answer:x = 1.153846153846154y = -1.923076923076923Step-by-step explanation:Multiply 7x - y = 12 by -4 and then add it to 2x - 4y = 10 2x - 4y = 10+(-4( 7x - y = 12)) -26x = -30 [tex]\frac{-26x}{-26} = \frac{-30}{-26}[/tex] x = 1.153846153846154Then plug in x to get y. 2(1.153846153846154) - 4y = 10 2.307692307692308 - 4y = 10 -2.307692307692308 -2.307692307692308 -4y = 7.692307692307692 [tex]\frac{-4y}{-4} = \frac{7.692307692307692}{-4}[/tex] y = -1.923076923076923
