Answer:
Step-by-step explanation:
3x+4y=29 .......(1)
6x+5y=43 .......(2)
Multiply equation (1) by 2
6x + 8y = 58......(3)
Substracting (2) from (3)
8y - 5y = 58 - 43
3y = 15
Dividing by 3
3y/3 = 15/3
y = 5
Substituting y = 5 into (2)
6x+5y=43
6x + 5(5) = 43
6x + 25 = 43
6x = 43 - 25
6x = 18
Dividing by 6
6x/6 = 18/6
x = 3
What we have to find in this question
Hello!
So, Jessie made 7 stacks of dimes and 8 stacks of nickels.
Each stack of dimes has 6 dimes.
Each stack of nickels has 5 nickels. Multiply:
6 × 7 = 42
8 × 5 = 40
Then she finds another dime and another nickel.
42 + 1 = 43
40 + 1 = 41
43 + 41 = 84
ANSWER:
Jessie has 43 dimes, 41 nickels, and 84 coins in all.
