Question

5. set up an equation for the following cases:

(g). Irfan has 27 marbles. His marbles are 7 more than five times Parmit has. (Take number of marbles of Parmit as z)​

Answer 1

Answer:

let us consider irfan has (x) number of marbles

i.e. x = 27 . . . . (given)

and parmit has (z) number of marbles

mathematical equation :

∴ x = 5 z +7

but (x = 27)

∴ 27 = 5 z + 7

∴ 5 z = 27 - 7

∴ z = 20 ÷ 5

∴ z = 4

so parmit has 4 marbles
