3) solve for x. −1/2(x 2) 11/2 x=3

1 answer:

3 0

-1/2(x + 2) + 11/2 + x = 3
-1/2x - 1 + 11/2 + x = 3
1/2x + 9/2 = 3
1/2x = 3 - 9/2 = -3/2
x = -3/2 * 2 = -3
x = -3

13-3/2 you need to make a common denominator, so

26/2-3/2 then subtract the numerators, the denominator remains.

23/2 now simplify the fraction

11½ this is because 22/2+1/2=23/2, and 22/2=11, so 11+1/2 or 11½
