Question

Find the solution to this system: 5x-2y=-11 -2x+5y=17 Multiplying equation 2 by will create additive inverses for the x-coefficient

Answer 1

Explanation:

5x-2y=11

-2x+5y=17

eqn1×2=10x-4y=22

eqn2×5= -10x+25y=85

21y=107

y=107÷21

5x-2(107/21)=11

5x-(214/21)=11

105x-214=231

105x= 445

x=445/105=
