Solve two equations with two unknowns:

400x+120y=147.2
350x+200y=144

Correct answer:

x =  0.32
y =  0.16

Step-by-step explanation:


400x+120y=147.2
350x+200y=144

400•x+120•y=147.2
350•x+200•y=144

400x+120y = 147.2
350x+200y = 144

x = 8/25 = 0.32
y = 4/25 = 0.16

Our linear equations calculator calculates it.
