Answer:
1. Directly put 6 in place of x so it would be.
-5(6) + 2 = -4*7
-30 + 2 = -28
-28 = -28
2. Find the value of x.
-5x + 2 = -7*4
-5x = -28 - 2
-5x = -30
x = 6 (because 30 is divisible by 5 at 6)
3. Make Right hand side and Left hand side equal. To make it equal just put 6 in place of x.
(-5(6) + 2)/7 = -4
(-30 + 2)/7 = -4
-28/7 = -4
-4 = -4
RHS = LHS (hence proved x = 6)
