(hint : weight of first piece bex' then weight of second piece is 'x+7' , weight of third piece is 'x+4')
Answers
Step-by-step explanation:
let, the weight of first peice be = x
∵ the first peice is 7g lighter than second peice
∴ the second peice is 7g heavier than the first peice
∴ the weight of second peice = x+7
∵ the first piece is 4g heavier then the third peice
∴the third peice is 4g lighter than the first peice
∴the weight of third peice = x-4
∵total weight of pizza = 300g
∴weight of first peice + weight os second peice+ weight of third peice = 300g
x + (x+7) + (x-4) = 300
x + x + 7 + x - 4 = 300
x + x + x + 7 - 4 = 300
3x + 3 = 300
3x = 300 - 3
3x = 297
x = 297/3
x = 99
weight of first peice = x
= 99
weight of second peice = x + 7
= 99 + 7
= 106
weight of third peice = x - 4
= 99 - 4
= 9
