Question

linear equation:
2x+3y=28
3x-4y=-9
​

Answer 1

Answer:

2x = 28-3y

gather variable in one side and solve

Answer 2

⭐Solution⭐

✏given here

2x + 3y = 28...(1)

3x -4y = -9........(2)

Multiply by 3 and 2 in (1) and (2)

6x + 9 y = 84.....(3)

6x -8 y = -18...(4)

subtract its

we get

17y = 102

=> y = 102/17

=>y = 6

by (1) ,

2x +3×6 = 28

=> 2x = 28-18

=>x = 10/2

=>x = 5

⏩Thus:-

value of X = 5

Value of Y = 6
