Multiple Choice

Make x the subject of the equation

$$x-2y=10$$  

• x + 2y = 10

• -2y = x + 10

• x = 10 - 2y

• x = 10 + 2y

Multiple Choice

Make x the subject of the equation

$$x+5y=-3$$  

• x = 3 + 5y

• x = -3 + 5y

• x = 3 - 5y

• x = -3 - 5y

Multiple Choice

Make x the subject of the equation

$$3x-6y=3$$  

• x = 2y + 1

• y = -2y + 1

• y = -2y + 3

Multiple Choice

Make y the subject of the equation

$$-4x+2y=-8$$  

• y = 2x - 4

• y = -2x + 4

• y = 2x + 4
