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

8 - 1 = 7

6 plus 7 plus 8 equals 6 plus 8 plus 7, what property is that?That is the associative property.

The numbers are: 1 and -8

x=1

it is 28

8+y = 7+5y y-5y = 7-8 -4y = -1 y = 1/4

The original questions is in parenthesis,71 plus 2 = 10 22 plus 31 =8 111 plus 22 =7(71) 7+1 "plus" 2 (2) = 10, (22) 2+2 (plus) (31) 3+1=8, (111) 1+1+1 "plus" (22) 2+2=7

7n + 1 = 6n + 8 7n=6n+7 (minus 1 from each side) n=7 (7n-6n equals n, you are left with n=7)

2x + 1 = 82x = 7x = 7/2 = 3.5whew !

144 9+7 = 16 and 9*16 = 144

-7+3b = 4b-8 3b-4b = -8+7 -b = -1 b = 1

A = 77 + 5 + 8 = 20

If I am correct, 9 plus 7 equals 112.

It is an equation and the value of x is 7/19

you do 3 plus 5 first then you get 8 you have to find out what minus 7 equals 8
