Step-by-step explanation:
Y=-3.34 x=-8.89
Combine two equations
0x-1.5y=5.01
-1.5y/-1.5=5.01/-1.5
y=-3.34
Plug in the y value for in one of the equations to solve for x.
-2.1x + 4(-3.34) = 5.3
-2.1x -13.36= 5.3
-2.1x = 18.66
-2.1x/-2.1 = 18.66/-2.1
x=-8.89
Plug in both values to validate the answer. Keep in mind there was rounding so the equation will not 100% be correct.
2.1(-8.89) - 5.5(-3.34) =
-18.66 + 18.37 = -0.29
-2.1(-8.89) + 4(-3.34) = 5.309
