Answer:
The value of x is 2 and y is -5
Step-by-step explanation:
Here, y = - 5 and 5x - 6y = 40 are two given equations.
Substitution Method:
y = - 5 ...(1)
5x - 6y = 40 ...(2)
Now, put the value of y = - 5 in equation (2) we get,
5x - 6y = 40
5x - 6(-5) = 40
5x - (-30) = 40
5x + 30 = 40
Now, Subtract 30 from both side
5x + 30 - 30 = 40 - 30
5x = 10
Now, Divide by 5 from both side
5x ÷ 5 = 10 ÷ 5
x = 2
Thus, The value of x is 2 and y is -5
FOR VERIFICATION ONLY:
5x - 6y = 40
5(2) - 6(-5) = 40
10 - (-30) = 40
10 + 30 = 40
40 = 40
Hence, L.H.S = R.H.S
