Question

Does anyone know how to do this Or how to calculate this I already have apps like photomath so don't even suggest that

Answer 1

I'm not sure what the answers you have mean. sorry! I've solved the problem, though, if that helps at all.

4x + 10y = 57

2x + 5y = 38

5y = 38-2x

y = (38-2x)/5

4x + 10((38-2x)/5) = 57

4x + 2(38-2x) = 57

4x + 76 - 4x = 57

0x + 76 = 57

the answer is no solution because 76 $\neq$ 57
