2x-3y equals 3 5x-4y equals 4?

Answer 1

2x - 3y = 3 ------ Eq.1 multiply this by -5

5x - 4y = 4 ------ Eq.2 multiply rhis by 2

_____________________________________ the result after multiply both equation

-5 ( 2x - 3y = 3 )

2 ( 5x - 4y = 4 )

_________________

-10x + 15y = -15

10x - 8y = 8

_________________ by using the elimination method the result will be

7y = -7

y = -7/7 ,,,,,,,,,,, Y = -1

to find the value of X, put the value of Y in Eq.1 :

2x - 3y = 3

2x - 3(-1) = 3

2x + 3 = 3

2x = zero ,,,,,,,,,,, X = Zero
