Answer 2

Answer:

(i) x+4=9

x=9-4

x= 5

(ii) y-2=8

y=8+2

y=10

(iii) a\times10\ =\ 70

(iv) \frac{b}{5}=\ 6\

b= 30

(v) \frac{3}{4}\times t\ =\ 15\

t\ =\ 15\times\frac{4}{3}

t = 20

(vi) \frac{b}{5}=\ 6\

b\ =\ 6\ \times5\

b = 30

(vii) \left(\frac{1}{4}\times x\right)-\ 4\ =\ 4\

\frac{x}{4}-\ 4\ =\ 4\

\frac{x}{4}=4+4\

x\ =\ 8\times4

x= 32

(viii) 6y-6 = 60

6y = 60+6

6y = 66

y\ =\ \frac{60}{6}

y = 11

(ix) \frac{z}{3}+\ 3\ =\ 30\

\frac{z}{3\ }=\ 33

z\ =\ 33\times3

z = 99
