Explanation:

Let M&Ms be=x and Starburts be=y

According to first condition

4x+2y=8.34-eq no 1

According to second condition

2x+3y=6.15-eq no 2

now, multiplying eq no 1 by 3 and eq no 2 by 2 and subtracting eq no 2 from eq 1

12x+6y=25.02

-4x-6y=-12.3

8x=12.72

x=12.72/8

x=1.59

Putting the value of x in eq 1

4*1.59+2y=8.34

6.36+2y=8.34

2y=1.98

y=1.98/2

y=0.99

Hence,the m&ms costed 1.59 and Starbursts costed 0.99
