If: 2X+1 = 22 Then: X = 10.5
write and equation...22 - 2x = 822 - 22 - 2x = 8 - 220 - 2x = -14-2x = -14-2x/-2 = -14/-2x = 7
2x - 7 = 15 2x = 22 x = 11
22 12+2x = 33 2x = 33-22 = 11
2x + 22 = x Subtract x from both sides: x + 22 = 0 Subtract 22 from both sides: x = -22
8x - 22 = 2x + 28x - 2x - 22 = 2x - 2x + 26x - 22 = 26x - 22 + 22 = 2+ 226x = 24x = 24/6 = 4
-2x + 6 + 22 = -2x + 28
If: 2X+1 = 22 Then: X = 10.5
write and equation...22 - 2x = 822 - 22 - 2x = 8 - 220 - 2x = -14-2x = -14-2x/-2 = -14/-2x = 7
2x + 30 = 4x + 22 Subtracting 2x from both sides, 30 = 2x + 22 Subtracting 22 from both sides, 8 = 2x Dividing both sides by 2, 4 = x x = 4
2/7x = 8x = 8 x 7/2x = 28
22+2x = 37+6+x 2x-x = 37+6-22 x = 21
2x - 7 = 15 2x = 22 x = 11
22 12+2x = 33 2x = 33-22 = 11
2x + 22 = x Subtract x from both sides: x + 22 = 0 Subtract 22 from both sides: x = -22
int[e(2X) +e(- 2X)] integrate term by term 1/22 e(2X) - 1/22 e(- 2X) + C (1/4)e(2X) - (1/4)e(- 2X) + C ====================
2x + 33 = 4x + 11 -11 -11 2x + 22 = 4x -2x -2x 22 = 4x Divide each side by 4 x = 5.5
