Question

Edward solved the equation 4X + 1 = 5x +(-5)

Add 4 negative both sides
Add 5 negative to both side
=4
What’s was mistake

Answer 1

He should have added 5 to each side instead of -5

Explanation:

4X + 1 = 5x +(-5)

Subtract 4x from each side

4X-4x + 1 = 5x-4x +(-5)

Combine like terms

1 = x-5

Add 5 to each side

He should add 5 to each side ( we need to add the opposite of (-5)) to undo the adding of (-5)

1+5 = x-5+5

6 =x
