2x(4+8) = 2x(4) and 2x(8)

2x + 5 = 13 2x = 8 2x/2 = 8/2 x=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

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

x=-4

8

2x-4y=-8-2x......-2x-4y=-2x-8(-4y)/-4 | (-2x-8)/-4y=1/2x+2

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

4

2x-4=6x+8-8= -82x-12= 6x-2x= -2x-12= 4x/4=/4-3=x

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

It is the commutative property of addition.

No because x = 2

3x + 4 = 8 + 2xSubtract 4 from each side:3x = 4 + 2xSubtract 2x from each side:x = 4

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

x = 8y = -42x - y = 2(8) - (-4) = 16 + 4 = 20

x= 2 because 2x+4=16 4x2=8 8+2 or 8x2=16

x=2

6

x=12

At the point (2, 4).

2, 4, 6 and 8 respectively

(-2, 4)

no x would be 0.5 because two times 0.5 is 1 ( 2x ) and then add 7 equals 8 ( plus seven equals 8 )
