please tell me confirmed answer l have to write in important letter please tell​

Answer 1

Answer:

(i) 6+x = 7

(ii) 3+y = 12

(iii) $\sf \frac{1}{3} × \sf{x}$ = 10

(iv) $\sf \frac{1}{2} × \sf{x+y}$ = 5

(v) 7 - y

(vi) x - 7

(vii) $\Large \sf \frac{x}{y}$ - 2

(viii) $\Large \sf \frac{1}{3} y$ - 4x

(ix) $\Large \sf \frac{xy}{3}$ = z
