y=16 x= -4
2x+9 = 49-3x 2x+3x = 49-9 5x = 40 x = 8
3x-5=40x+3 Subtract 3x-5 from each side 0=37x+8 -8=37x x= -8/37
7x-40 = -3x Add 40 and add 3x to both sides:- 7x-40+40+3x = 3x-3x+40 10x = 40 Divide both sides by 10:- x = 4
7. 8x-40=2x+2 4x-20=1x+1 3x-21=0 3x=21 therefore x=7
4x + 10 + 3x = 40 - 3x 4x + 10 + 3x + 3x = 40 20x = 40 x = 2
3x + 2x = 40 5x = 40 x = 8
x + 3x = 40 4x = 40 x = 10.

10 - 3x = x - 2x + 40 10 - 3x = - x + 40 10 - 40 = 3x - x -30 = 2x -15 = x
y=16 x= -4
2x+9 = 49-3x 2x+3x = 49-9 5x = 40 x = 8
x+30 = 3x-50 x-3x = -50-30 -2x = -80 x = 40
7x-4 = 3x+36Add 4, it cancels out.. So,7x = 3x+40Now subtract 3x from 7x..4x = 40..40 divided by 4 is 10So, X= 10
3x-5=40x+3 Subtract 3x-5 from each side 0=37x+8 -8=37x x= -8/37
7x-40 = -3x Add 40 and add 3x to both sides:- 7x-40+40+3x = 3x-3x+40 10x = 40 Divide both sides by 10:- x = 4
7. 8x-40=2x+2 4x-20=1x+1 3x-21=0 3x=21 therefore x=7
