One soda and one taco costs $2.1. Two sodas and three tacos cost $5.15. Find the cost of a soda and a taco. Whoever answer this question will be the brainliest!!!

Soda costs $1.15 and taco costs $0.95.

Step-by-step explanation:

x + y = 2.1

2x + 3y = 5.15

Multiply the first equation by -2 to eliminate x

-2x - 2y = -4.2

2x + 3y = 5.15

Add

          y = 0.95

Find x with the original first equation

x + y = 2.1

x + 0.95 = 2.1

x = 2.1 - 0.95

x = 1.15
