Question

1. Solve for x and y: 5x - 2y = 1
3x + 2y = 7

Answer 1

Answer:

1 is the right answer....

Answer 2

Step-by-step explanation:

5x - 2y = 1

3 x + 2y = 7

adding both the equations,

we get

5x+3x+2y - 2y = 1+ 7

8x = 8

x = 8÷ 8

x = 1

now,

3x + 2y = 7

3 * 1 + 2y = 7

2 y = 7-3

y = 4÷ 2

y = 2
