32-5x=3x+8 32-5x-8=3x+8-8 24-5x=3x 24-5x+5x=3x+5x 24=8x x=24/8=3
If: 3x+8-x = 5x-4 Then: x = 4
The answer is -8.
5x+(6-3x)+8=5x+6-3x+8=2x+14 2x + 14
3x+2y=20 5x-2y=1 (3x+2y) + (5x-2y)= 20+1 3x+5x= 21....... 8x=21.........x=2 5/8 Subsitute x=3(2 5/8)+ 2y=20........... 7 7/8 +2y=20.........2y= 20- 7 7/8....... y=6 1/16
The value of x is: x=7/8. Work: 5x-3=4-3x +3 +3 ________ 5x=7-3x +3x +3x ________ 8x=7 /8 /8 ________ x=7/8
3x = 7-5x 8x=7 x = 7/8 x = 0.875
32-5x=3x+8 32-5x-8=3x+8-8 24-5x=3x 24-5x+5x=3x+5x 24=8x x=24/8=3
9x+7
If: 3x+8-x = 5x-4 Then: x = 4
The answer is -8.
5x + 8 = 3x + 25x - 3x = 2 - 82x = -6x = -6/2x = -3Check:5(-3) + 8 = 3(-3) + 2-15 + 8 = -9 + 2-7 = -7
5x+(6-3x)+8=5x+6-3x+8=2x+14 2x + 14
3x+2y=20 5x-2y=1 (3x+2y) + (5x-2y)= 20+1 3x+5x= 21....... 8x=21.........x=2 5/8 Subsitute x=3(2 5/8)+ 2y=20........... 7 7/8 +2y=20.........2y= 20- 7 7/8....... y=6 1/16
5x + 5 = 8 -3x 5x = 3 -3x 8x = 3 x = 0.375
3x + 8
0. 7 - 3x = 5x + 13 1. 7 - 8x = 13 2. -8x = 5 3. x = -5/8.
