Question

the solution of equations 3x+4y=10 and 2x-2y=2 is​

Answer 1

refer the attachment for the answer

we have to

1. multiply equation 1 with 2 and equation 2 with 3 to make terms equal
2. go through elimination method

Answer 2

Step-by-step explanation:

3x + 4y = 10 .................eq1 ×1

2x - 2y = 2 ...................eq2 ×2

= 3x + 4y = 10

4x - 4y = 4

= 7x = 14

= X = 14/2

= X = 7

putting the value of X in eq 1.

3×7 + 4y = 10

= 21 + 4y = 10

= 4y = 10-21

= 4y = -11

= y = -11/4

Therefore, the value of X= 7 and y = -11/7
