Substitution property.
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
4 + x = 2x Subtract 'x' from both sides 4 = 2x - x x = 4 Verification 4 + 4 = 2(4) 8 = 2 x 4 = 8 True!!!!!
2x+4=82x=8-4 (you subtract 4 on both sides)2x=4 (you then divide by 2 on both sides)x=2
2x(4+8) = 2x(4) and 2x(8)
2x + 5 = 13 2x = 8 2x/2 = 8/2 x=4
2x-4=6x+8-8= -82x-12= 6x-2x= -2x-12= 4x/4=/4-3=x
x = 4
y=8 y = 2x y = 2(4) <-- substitute 4 for x y = 8 <-- this is your answer
2x-4y=-8-2x......-2x-4y=-2x-8(-4y)/-4 | (-2x-8)/-4y=1/2x+2
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 + 8 = 3x - 4 Subtract 2x from both sides: 8 = x - 4 Add 4 to both sides: 12 = x
4 + x = 2x Subtract 'x' from both sides 4 = 2x - x x = 4 Verification 4 + 4 = 2(4) 8 = 2 x 4 = 8 True!!!!!
2x+4=82x=8-4 (you subtract 4 on both sides)2x=4 (you then divide by 2 on both sides)x=2
