Question

5. Solve these equations using the guess and check method.

h + 21 = 38

b) S-17 = 23

$ c) g + 28 = 50 d)

2x + 18 = 42 e)

f) 3p + 24 = 57

g) 7+-5=2

-=2 49 - 17 = 19

h) En + 15 = 17

k) :+9 = 12 1

i) + 18 = 33 5 32 + LU-8 = 0 j e2+9= 34 ] 0 34 ​

Answer 1

Answer:

a) h+21=38

or, h=38-21

or, h=17

b) s-17=23

or, s=23+17

or, s=40

c) g+28=50

or, g=50-28

or, g=22

d) 2x+18=42

or, 2x=52-18

or, 2x=32

or, x=34/2

or, x=16

e) 3p+24=57

or, 3p=57-24

or, 3p=33

or, p=33/3

or, p=11

f)
