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.
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.
To solve the equation y^7 - 3 = 39, Beejal starts by adding 3 to both sides of the equation. This step is done to isolate the variable term.
y^7 - 3 + 3 = 39 + 3
Simplifying the equation, Beejal gets:
y^7 = 42
Next, Beejal proceeds by multiplying both sides of the equation by 7. This step is done to eliminate the exponent and solve for y.
7(y^7) = 7(42)
Simplifying further, Beejal gets:
7y^7 = 294
To solve the equation y^7 - 3 = 39, Beejal starts by adding 3 to both sides of the equation. Adding 3 to both sides will help isolate the term involving y^7.
So the equation becomes:
y^7 - 3 + 3 = 39 + 3
Simplifying the equation, we have:
y^7 = 42
The next step Beejal takes is multiplying both sides of the equation by 7. This is done to isolate the variable y^7.
Multiplying both sides by 7, we get:
7 * y^7 = 7 * 42
Simplifying the equation further:
7y^7 = 294
So the correct first step is to add 3 to both sides of the equation, and then the next step is to multiply both sides by 7.
