What is the standard form of the

Linear Equation 5x = 8 - y?

• 5x - y = 8

• 5xy = 8

• 5x + y = 8

• y + 5x = 8

What is the standard form of the

Linear Equation 4y + 3x = 7

• -3x - 4y = 7

• 3x - 4y = 7

• -3x + 4y = 7

• 3x + 4y = 7

What is the standard form of the

Linear Equation x = 1 + 7y

• 7x + y = 1
