Consider the following system of equations:
equation 1: 3x + y = 5
equation 2: 5x – 4y = -3
what is the solution to this system?
(to answer this question, we need to know the value of y.)
o (1.8)
o (1,2)
o (1,1)
o (1.3)

x=1, y=2. (1, 2).

Step-by-step explanation:

3x+y=5

5x-4y=-3

4(3x+y)=4(5)

5x-4y=-3

12x+4y=20

5x-4y=-3

17x=17

x=17/17

x=1

3(1)+y=5

y=5-3

y=2
