What is the first step in isolating y in the equation 3x + 5y = 24?

• Divide each term by 5

• Multiply each term by 5

• Add 3x to each side

• Subtract 3x from each side

After isolating y in the equation 3x + 5y = 24, what is the resulting expression for y?

• y = 24/5 + 3x/5

• y = 24/5 - 3x/5

• y = 24/5 / 3x/5

• y = 24/5 * 3x/5

In the equation -2y + 5x = 16, what is the first step to isolate y?

• Add 5x to each side

• Subtract 5x from each side

• Multiply each term by -2

• Divide each term by -2

What is the final expression for y in the equation -2y + 5x = 16 after isolating y?

• y = -8 - 5x/2

• y = -8 + 5x/2

• y = 8 + 5x/2

• y = 8 - 5x/2

How do you isolate b in the equation a + b = c?

• Add a to each side

• Subtract a from each side

• Multiply each term by a

• Divide each term by a

What is the expression for b in the equation ab = c after isolating b?

• b = c + a

• b = c / a

• b = c - a

• b = c * a

Which of the following is an equivalent format for b = (4 - a) / c?

• b = 4 / c - a / c

• b = 4 * c - a * c

• b = 4 - a * c

• b = 4 + a / c

What is the most simplified form of b = (4 - a) / c?

• b = 4 - a / c

• b = 1 / c * (4 - a)

• b = 4 * c - a

• b = 4 / c - a / c
