Question 1 (1) Answers I think This is help for you

Answer 2

Answer:

(i)

$-2(\frac{3x}{2} +2) = 1\\\frac{3x}{2} +2 =\frac{-1}{2} \\\frac{3x}{2} = \frac{-5}{2} \\x = \frac{-5}{3}$

(ii)

2y +1/2 = 3/2

2y = 3/2 - 1/2 = 1

y = 1/2

(iii)

x/4 + 3 = 7

x/4 = 7-3 = 4

x = 16

(iv)

(3x-1)/5 - x/7 = 3

(3x-1)7 - 5x = 3*5*7

21x - 7 - 5x = 105

16x=105+7=112

x=112/16=7

(v)

$\frac{y+7}{3} = 1+ \frac{3y-2}{5}$

$\frac{y+7}{3} = \frac{5+3y-2}{5}$

5y+35 = 15+9y-6

9y-5y= 35-15+6

4y= 26

y=13/2

(vi)

$\frac{2x-3}{5} +\frac{x+3}{4} = \frac{4x+1}{7} \\7{\frac{(2x-3)4+(x+3)5}{20}} = 4x+1$

7{8x-12+5x+15} = 4x+1

56x-84+35x+105=4x+1

87x=-20

x= -20/87

(vii)

$\frac{3}{4}(7x-1)-(2x-\frac{(1-x)}{2}) = x+\frac{3}{2} \\\frac{3}{4}(7x-1)-(\frac{4x-1+x}{2}) = x+\frac{3}{2} \\\frac{21x}{4} -\frac{5x}{2} -x=\frac{3}{2}+\frac{3}{4}-\frac{1}{2}$

7x/4=7/4

x=1

(viii)

$\frac{x+2}{x-2} =\frac{7}{3}$

3(x+2)=7(x-2)

3x+6=7x-14

4x=20

x=5

Hope it helps!
