The adding numbers keep going up, and the subtracting numbers keep going down: # Plus 4 # Subtract 3 # Plus 5 # Subtract 2 # Plus 6 # Subtract 1
3x+8 = 2x+5 Subtract 2x from both sides: x+8 = 5 Subtract 8 from both sides: x = -3
5y + 3 = 6y + 8 Subtract 5y from both sides: 3 = y + 8 Subtract 8 from both sides: -5 = y So y = -5
3x+2=2x+8x=63x+2 = 2x + 8; first subtract 2x from both sidesx+2=8; then subtract 2 from both sidesx=6
y/2 + 8 = 13 Subtract 8 from both sides: y/2 = 5 Multiply both sides by 5: y = 10
6x + 8 = x + 6 Subtract x from each side: 5x + 8 = 6 Subtract 8 from each side: 5x = -2 Divide both sides by 5: x = -0.4 x = -0.4
2+2-8=-4
16 / 8 + 2 * 5 - 21 / 7 = 2 + 10 - 3 (multiplication and division first) = 9
First subtract 4-2, which equals 2. Then add 2+8=10.
If you mean 8 and 7/12 subtract 2 and 3/8 then it is 6 and 5/24
1. Subtract 25 2. Then subtract 6 3. Then subtract 12 4. Then subtract 2 5. Then subtract 10 6. Then subtract 15 7. Then subtract 7 8. Then add 3 X 1/2 9. Then add 8
