40 + 9 + 12 = 61
40 + 9 = 5y + 9 Since 9 is present on both sides of the equation,therefore we can strike it off on both sides,the remaining equation being 40 = 5y or 5y = 40 5y = 40 or y = 40/5 Therefore,y = 9 .
3( 30 + 40 ) - 6 + 9 3 (70) - 6 + 9 210 - 6 + 9 = 213

25+15=40+9=49

40 6 + 46 - 3 - 9 = 40
-9-6+12h+40=22

5/40 + 4/40 = 9/40

7/8 + 9/10 = 35/40 + 36/40 = 71/40 = 131/40
