You find x. Oh! There it is!! ^ See?

5x + 2 = 22 5x = 22 - 2 5x = 20 5x/5 = 20/5 x=4

5x+1=20 5x=20-1 5x=19 5x/5=19/5 x=19/5

5x+y=-7 3x+y=15 8=D

x=8

(x-3)(x-2)

5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2

-5x+1 = 6x -5x-6x = -1 -11x = -1 x = 1/11

its answer is probably -4.4 best of luckk!!!!!:)

Then x = 6 Therefore; 5x + 3 = 33 First you have to solve the value of X: 8X + 5X + 2X +4X = 114; OR 19x = 114. When you divide both sides of the equation by 19 to solve for X, you find that X = 6. Ergo, 5X + 3 = 30 + 3 = 33; hence, 5X + 3 = 33.

5x+3+x=24 6x+3=24 6x=21 x=3.5

3x + 2x = 5x. 5x= (-4) X = (-4)/5 x= -0.8

That equation has no solution. There is no possible number that's equal to 18 more than itself.

If: 5x+1 = 21 Then: 5x = 21-1 => 5x = 20 Divide both sides by 5 and so x = 4

5x + 9 = 4Subtract 9 from each side:5x = -5Divide each side by 5:x = -1

5x + 3 = 4xSubtract 3 from each side:5x = 4x - 3Subtract 4x from each side:x = -3
