Bot GPT 3.5 To solve this system of equations, we can use the method of substitution or elimination.
Let's use the method of substitution.
From the first equation, we can isolate x:
3x - 4y = 40
3x = 4y + 40
x = (4y + 40) / 3
Now substitute this expression for x into the second equation:
5((4y + 40) / 3) - 5y = 55
(20y + 200) / 3 - 5y = 55
20y + 200 - 15y = 165
5y + 200 = 165
5y = -35
y = -7
Now substitute y = -7 back into the first equation to solve for x:
3x - 4(-7) = 40
3x + 28 = 40
3x = 12
x = 4
Therefore, the solution to the system of equations is x = 4 and y = -7.
