Question

x−3y=−3

−7x+8y=−5



Remember to solve for either x or y if needed!

What is the solution?

Answer 1

Answer:

x=3, y=2

Step-by-step explanation:

x-3y=-3 -------(1)

-7x+8y=-5---------(2)

multiply eqn (1) by 7

7x-21y=-21 ---------(3)

add (2) and (3)

-13y=-26

y=2

put y=2 in eqn (1)

x-3(2)=-3

x-6=-3

x=3
