Question

Solve the system of equations .625x - y = -9.625 -65x - y = -5

Answer 1

Here, 0.625x - y = -9.625
y = 0.625x + 9.625

Substitute the value of y in 2nd equation, 
-65x - (0.625x + 9.625) = -5
-65x - 0.625x -9.625 = -5
-65.625x = 9.625 - 5
x = -4.625/65.625
x = -0.070

Now, substitute it in first equation, 
-65(-0.070) - y = -5
4.58 + 5 = y
y = 9.58

In short, Your Answer would be: (-0.070, 9.58)

Hope this helps!
