Question

75-х=75 ,89-у=0.4 +х=64

Answer 1

75-х=75   4+х=64     89-у=0

-х=0         х=64-4     -у=-89

х=0           х=60         у=89

Answer 2

To solve this system of equations for x and y, we can start by isolating one variable in each equation and then substituting it into the other equations. Let's solve it step by step:

1. 75 - x = 75 Subtract 75 from both sides: -x = 0

2. 89 - y = 0.4 + x Since we found that -x = 0 in the first equation, we can substitute this into the second equation: 89 - y = 0.4 Now, subtract 0.4 from both sides to isolate y: 89 - 0.4 = y y = 88.6

So, the solution to the system of equations is: x = 0 y = 88.6
