Form new equations by carrying action (given in brackets) :
(i) $ 2 x+3=13 $ [Multiply by 2 ]
(ii) $ 3 y-3=21 $ [Add 5]
(iii) $5 x+14=24 $ [Subtract 6]
(iv) $ 10 y+6=36 $ [Divide by 2]
Solution:
i) $2x+ 3 = 13$ [Multiply by 2]
=>$2(2x+3) = 2\times13$
=>$4x + 6 = 26$
ii) $3y-3 = 21$ [Add 5]
=>$3y - 3 + 5 = 21 + 5$
=>$3y + 2 = 26$
iii) 5x + 14 = 24 [Subtract 6]
=>$ 5x + 14 - 6 = 24 - 6$
=>$5x + 8 = 18$
iv) 10y + 6 = 36 [Divide by 2]
=>$5y + 3 = 18$
