(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
8x + 38 = 2x + 2 The first thing you want to do is get all the variables on one side and all the stand-alone numbers on the other side. To do this, you just do the opposite of what the sign is (Ex: Since it is "plus 38" on the left side, to get it to the right we subtract 38) 8x = 2x + 2 -38 Now you can simplify the right side: 8x = 2x -36 And then you want to get the variables on the left side of the problem. So since 2x is positive, you want to subtract 2x from both sides of the equation. 8x - 2x = -36 Simplify the left side: 6x = 36 And then from there you can divide both sides by 6. x = 6
