Answer:
Chips= $1.79
Soda= $1.12
chips: $1.79
soda: $1.12
Step-by-step explanation:
x = chips cost
y = soda cost
4x + 3y = 10.52
3x + 2y = 7.61
i used the elimination method by multiplying the first equation by -2
and the second equation by 3
-8x - 6y = 21.04
9x + 6y = 22.83
x = 1.79
solve for 'y':
3(1.79) + 2y = 7.61
5.37 + 2y = 7.61
2y = 2.24
y = 1.12
21+j=55
It says sum, which means to add(+). So you add 21 and j (21+j) and that equals 55 (=55). Then you add all the pieces together and you get 21+j=55
