x=7
5x-2 = 3x-6 5x = 3x - 6 +2 5x = 3x - 4 5x - 3x = -4 2x = -4 x = -2
So, we have 3x = 4 for some number x. We will solve for x. 3x = 4 (1/3)*(3x) = (1/3)*(4) [multiplied by (1/3) on both sides] x = 4/3
3x + 2x = 5x. 5x= (-4) X = (-4)/5 x= -0.8
4 + 3x = -8subtract four from each side3x = -12divide each side by threex = -4
3x = (96-75) 3x = 21So X = 7
3x=96-75 3x=21 x=7
Solve for x: 3x=(96-75) 96-75= 21 / 21:3= 7
x=7
7
2y-3x=4
3x + 4= 7 3x= 7-4 3x/3 = 3/3 x=1
3x - 4 = -2 The answer is x=2/3
First you simplify: 3x=21 Then you divide both sides by 3: x=7
You can't really sove that question. there's no equal sign.. if you mean 3x times 96 = 75, then it would be: 288x = 75, x= 0.260
126
12(3x-8)=48Distribute the 12 to the 3x and -8, that would give you 36x-96=48Next add the -96 to both sides of the equation resulting in 36x=144Lastly divide both sides of the equation by 36 giving you the result of x=4
