Question

Solve equation y - 4 = 3

Answer 1

Answer: y = 7

Explanation:

y - 4 = 3

add 4 to both sides.

this becomes y - 4 + 4 = 3 +4

y + 0 = 7

y = 7

Answer 2

y = 7

Explanation:

y-4 = 3

Add 4 to both sides of the equation so the y is 'isolated' (alone).

y - 4 + 4 = 3 + 4

Now simplify

y-0 = 7

y = 7
