The question contains two equations:5x - 6y = 15 5x + y = 2 There are no inequalities in the question.
(3, 3)
the simplest form of 5x + 3y +2x - 6y is 7x-3y
3x + 6y = 48 .... Eq.1-5x + 6y = 32 .... Eq.2 .... in another way 6y = 5x + 32Put the value of Eq.2 in Eq. 13x + 5x + 32 = 488x = 48 - 328x = 16x = 16/8 ...... X = 2To find the value of Y put the value of X in Eq.26y = 5x + 326y = 5(2) + 326y = 10 + 326y = 42y = 42/6 ...... Y + 7
- 5x - 6y - 8 = 0Add (5x + 8) to each side:- 6y = 5x + 8Divide each side by -6 :y = (-5/6)x - 8/6y = - 5x/6 - 4/3
-5x + 6y = 24 6y = 5x + 24 y = 5/6 x + 4 the slope is 5 6

-5x + 6y = 30At the x-intercept, y=0:-5x = 30 ==> x = -6At the y-intercept, x=0:6y = 30 ==> y = 5
the simplest form of 5x + 3y +2x - 6y is 7x-3y
There are 2 unknowns
5x -6y=-30 5x-6y=30 (2x+3y) (2x-3y)=30 4x+6y=30 4x=30 x=30/4
3x + 6y = 48 .... Eq.1-5x + 6y = 32 .... Eq.2 .... in another way 6y = 5x + 32Put the value of Eq.2 in Eq. 13x + 5x + 32 = 488x = 48 - 328x = 16x = 16/8 ...... X = 2To find the value of Y put the value of X in Eq.26y = 5x + 326y = 5(2) + 326y = 10 + 326y = 42y = 42/6 ...... Y + 7
