Question

Find out which of the following equations will have x = 2 & y = 1 as its solution. *. 2x + 3y = 7
2x + 5y = - 9
5x + 3y = 14
3x + y = 10​

Answer 1

Step-by-step explanation:

when x = 2 & y = 1

2x + 3y = 7

2*2 +

Answer 2

Answer:

a) p(x) => 2x + 3y = 7

2(2) + 3(1) = 7

4 + 3 = 7

7 = 7

b) 2x + 5y = -9

2(2) + 5(1) = -9

4 + 5 = -9

9 = -9

c) 5x + 3y = 14

5(2) + 3(1) = 14

10 + 3 = 14

13 = 14

d) 3x + y = 10

3(2) + 1 = 10

6 + 1 = 10

7 = 10

a) equation have x=2 & y=1 as its solution
