2.2x+3y=15.25 4.6x+2.1y=18.325USING ELIMINATIONSHOW WORK PLEASE
1 answer:
-4.6(2.2x+3y=15.25) = -10.12x - 13.8y = -70.15
2.2(4.6x+2.1y=18.325) = 10.12x - 4.62y = 40.315
simplify
-4.62y = -29.835
divide both sides by -4.62 to isolate y
y= 6.46
2.2x + 3 (6.46) = 15.25
2.2x + 19.38 = 15.25
subtract 19.38 to both sides
2.2x = -4.3
divide 2.2 to both sides
x= -1.95
I hope that this helped :)
