Question

4x+2y=5 , 2x-3y=13 pair of equations to two decimal places of accuracy. ​

Answer 1

x = 2.56, y = -2.63

Explanation:

I first multiplied the second equation by two, getting

4x-6y = 26

I then subtracted the equations

4x+2y = 5

- 4x-6y = 26

--------------------

8y = -21

y = -2.63

with y solved, I plugged it into the second equation to get x:

2x-3(-2.63) = 13

2x+ 7.89 = 13

2x = 5.11

x = 2.56

I hope this helped! ;D
