one-half of a number & thirteen is 22

Answer 1

(X+13)/2 = 22

X+13 = 44

X = 31

Or, maybe the problem reads

(X/2) + 13 = 22

X/2 = 22-13 = 9

X/2 = 9

X = 2(9) = 18

the problem is a little ambiguous as to whether "& 13" applies to x or to x/2

PENDAS order of operations does division first before addition

so X=18 is probably the intended answer

Answer 2

.5x + 13 = 22

.5x +13 -13 = 22 - 13

.5x = 9

.5x * 2 = 9 * 2

x = 18
