Answer:
x = 3.405; y = 5.238
Steps:
1.) cancel out the x’s
2(5x+2y=27.50) -5(2x+5y=33.00)
10x+4y=55 -10x-25y=-165
2.) solve the equation and subtract them
10x+4y=55
-10x-25y=-165
———————
-21y=-110
3.) divide -21 by -110 to isolate the y
-21/-110=5.238 (about)
y=5.238
4.) plug y back into one of the equations
2x+5(5.238)=33.00
5.) solve for x
2x+26.19=33.00
-26.19 -26.19
—————————
2x=6.81
6.) divide 2 by 6.81
2/6.81=3.405
x=3.405
x = 3.405; y = 5.238
