(8x - 8) - (6x - 10) = ?8x - 8 - 6x + 10 = ?8x - 6x + 10 - 8 = ?2x + 2 = ?The answer is (2x + 2)
Remember in algebra any operation you do to one side of the equaution and also to the other side does not affect the eqaution 8x + 7 = 2x + 49 subtract 2x from both sides 6x + 7 = 49 subtract 7 from both sides 6x = 42 divide both sides by 6 x = 7
They can be simplified to: 6x+2x = 8x
8x + 20 = 4 (2x + 5)
8x - 4x + 7 = 94x + 7 = 94x = 9-74x = 2x = 4/2x = 1/2x = 0.5
(8x - 8) - (6x - 10) = ?8x - 8 - 6x + 10 = ?8x - 6x + 10 - 8 = ?2x + 2 = ?The answer is (2x + 2)
I would subtract [ 2x (4x + 9) ] .
Subtract 8x from each side: -6 = 2x + 6;Subtract 6 from each side: -12 = 2x;Divide each side by 2: x = -6
To solve this equation, we will first subtract 2x from each side:8x=2x+6 (8x minus 2x=6x)6x=6Now, to isolate x, we must divide out the 6:6x=6 (6x divided by 6= x)x=1If 8x=2x+6, x=1
16 + 2x = 10 + 8x Subtract 2x from both sides: 16 = 10 + 6x Subtract 10 from both sides: 6 = 6x Divide both sides by 6: 1 = x
3x+2=2x+8x=63x+2 = 2x + 8; first subtract 2x from both sidesx+2=8; then subtract 2 from both sidesx=6
8x - 5 = 2x + 5 Add 5 to both sides: 8x = 2x + 10 Subtract 2x from both sides: 6x = 10 Divide both sides by 6: x = 10/6 = 5/3 or 1.66... recurring.
Subtract: 2x = -20Divide by 2: x = -10
8x + 2 = 6x + 10 Subtract 6x from both sides: 2x + 2 = 10 Subtract 2 from both sides: 2x = 8 Divide by 2: x = 4 x = 4
8X + 5 = 2X - 25 subtract 2X from each side 6X + 5 = -25 subtract 5 from both sides 6X = - 30 divide both sides by 6 X = - 30/6 I checked with my calculator, It checks -35 = -35
2x
3x + 2x - 8x + 2x = -x
