To solve the equation y7 − 3 = 39, Beejal should start by adding 3 to both sides of the equation. This is because we want to isolate the term containing y on one side.
After adding 3 to both sides, the equation becomes:
y7 = 42
Next, Beejal should multiply by 7 on each side. This is because if we want to find the value of y, we need to get rid of the coefficient of 7 on the left side.
After multiplying by 7 on each side, the equation becomes:
7y = 294
Therefore, Beejal adds 3 to both sides and then multiplies by 7 on each side.
Beejal is solving the equation y7 − 3 = 39.(1 point) As a first step, he starts by adding ___ to both sides of the equation, and then continues by multiplying by 7 on each side.
