b. 16+z=10
c. -18+n=-22
d. w-32=45
e. 19-t=27
f. 5-(-25)=33
g. -127+r=139
h. 2+x=32+24
i. x+(-18)
j. -29+x+29=5
k. t+(-23+45)=-5
l. (z-12)-28=1-2

Answer 1

a) x+5=2 → x=2-5 → x=-3

b)16+z =10 → z =10-16 → z = -6

c) -18+n= -22 → n = -22 +18 → n= -4

d) w-32 = 45 → w = 45 +32 → w = 77

e) 19 - t = 27 → -t =27 - 19 → -t = 8 → t = -8

f) 5 - (- 25) = 33

g) -127 + r =139 → r = 139 +127 → r = 266

h) 2 +x = 32 + 24 → x =32 + 24 -2 → x = 54

i) x + (-18) → x- 18 =0 → x = 18

j) -29 + x + 29 =5 → x = 5+29-29 → x=5

k) t + (-23 + 45) = -5 → t -23 +45 = -5 → t = -5 +23 -45 → t = -27

l) (z -12) -28 = 1 - 2 → z -12 -28 = 1-2 → z= 1-2+12+28 → z = 39
