Question

What number should replace e
(i) 3 (n + 6) = (3 x 5) + (3 x 6)
(ii) (7 x 4) + (n x 3) = 7 (4+3)
(iii) (
98) + (8 x 8) = (9+8) n
Multiply by suitable arrangen
(i) 20,5,-8,7 (ii) 25,4​

Answer 1

Answer:

(i) 3n+18=15+18=33.

3n=33-18.

3n=15.

so,n=5.

(ii) 28+3n=49.

3n=49-28=21.

n=7.

(iii) 98+64=17n.

162=17n.

n=162/17=9 integer 9/17.
