Answer 1

a. 2y-5=17

2y=17+5

2y=22

y=22/2=11

b. 3m+8=10-2m

3m+2m=10-8

m=2

c. 12=6+3x

12-6=3x

6=3x

x=6/3=2

d. 17- (h+1)=6

16-h=6

16-6=h

h= 10

e. 2p=p+10

2p-p=10

p=10

f. 5(x-3)=2(x+3)

5x-15=2x+6

5x-2x=6+15

3x=21

x=7

g. 5x+2/36=7x-5/48

(5x+2)(48)=(7x-5)(36)

240x+96=252x-180

96+180=252x-240x

276=12x

x=23

h. n/2+17/5=17/2+2/5

n/2-17/2=-17/5+2/5

n-17/2=-15/5

n-17/2=-3

n-17=-3x2

n-17=-6

n=-6+17

n=11

i. 3/4x - ½= 18 ¼

3/4x=18 ¼+½

3/4x= 18 3/4

x=18 3/4 ÷ 3/4

=18 3/4 x 4/3

=75/4x4/3

x =75/3=25
