Divide each side of the inequality by -3 .
I wanted to work part of it and leave the rest for you to do,
but that won't happen. As soon as you do the first step as
I've suggested, the answer will be there, staring at you, with
nothing more left to do.
If: 3x-4 = or > 11 Then: 3x = or > 15 So: x = or > 5
4x+7-3x = 15 4x-3x = 15-7 x = 8
-(3x -2) = 17 -3x + 2 = 17 - 3x = 15 x = -5
-3x + 5 = 20 -3x = 15 x = -5
3x-5y=15 The equation-5y=15-3x Subtract 3x from both sidesy=-3+.6x Divide both sides by -5
solve -3x-3y=-15
If: 3x-4 = or > 11 Then: 3x = or > 15 So: x = or > 5
4x+7-3x = 15 4x-3x = 15-7 x = 8
4
-(3x -2) = 17 -3x + 2 = 17 - 3x = 15 x = -5
3x-8>15
-3x + 5 = 20 -3x = 15 x = -5
3x-5y=15 The equation-5y=15-3x Subtract 3x from both sidesy=-3+.6x Divide both sides by -5
x + 5 = 4x/3 Solve for x multiply both sides of the equation by 3... 3 * (x + 5) = 3 * (4x/3) 3x + 15 = 4x subtract 3x from both sides of the equation (3x + 15) - 3x = (4x) - 3x 15 = x x = 15
Treat the "greater than" sign as an equal sign, so subtract 3 from 12 and you get 9. Divide the 9 by three and you get 3. You should get x > 3.
"x3" is not an inequality. An inequality will have one of the following signs: less-than, less-than-or-equal, greater-than, greater-than-or-equal. for example: 3x - 5 < 15
5 - 3x = 17 is not an inequality, it is an equation. Inequalities never have equal signs in them, only "less/greater than", and "less/greater than or equal to" signs.To solve the equation:Step 1: Add 3x to both sides: 5 = 17 + 3xStep 2: Subtract 17 from both sides: -12 = 3xStep 3: Divide both sides by 3: x = -4The solution to the equation is x = -4
