y=8 y = 2x y = 2(4) <-- substitute 4 for x y = 8 <-- this is your answer

According to the distributive property, 7x(4y + 4) - 8(4y + 4) = (7x - 8)(4y + 4). Is this question true or false?>

2x + 8 = 3x - 4 Subtract 2x from both sides: 8 = x - 4 Add 4 to both sides: 12 = x

2x - 4y = 8 2x = 4y + 8 x = 2y + 4

2x+4=82x=8-4 (you subtract 4 on both sides)2x=4 (you then divide by 2 on both sides)x=2

x=-4

8

According to the distributive property, 7x(4y + 4) - 8(4y + 4) = (7x - 8)(4y + 4). Is this question true or false?>

2x + 8 = 3x - 4 Subtract 2x from both sides: 8 = x - 4 Add 4 to both sides: 12 = x

2x - 4y = 8 2x = 4y + 8 x = 2y + 4

2x+4=82x=8-4 (you subtract 4 on both sides)2x=4 (you then divide by 2 on both sides)x=2
