Answer:

Step-by-step explanationMultiply e second equation with 2, then combine equations to get x first. You can find

x=9\7 and y=17\7

3x−2y=−1

4x+2y=10

(when you multiply the second equation with 2)

Combine these equations now, yielding

7x=9

Therefore you can easily get

x=9\7

Now put this value in the first original equation to find y

3×(9\7)−2y=−1

27\7−2y=−1

27\7+1=2y

34\7=2y

y=17\7

or

y=2×(3\7)
