Question

5[5y -6] = 4[y -7]
solve the equation by balancing the equation

Answer 1

a(b-c) = axb - axc

25y - 30 = 4y - 28

25y - 30 + 30 = 4y - 28 + 30

25y = 4y - 2

25y - 4y = 4y - 4y - 2

21y/21 = 2/21

X = 2/21

Answer 2

21y = 23

Explanation:

1. 25y-30 = 4y-7

2. 25y-4y = 30-7 (move like terms over to each side)

3. 21y = 23
