It can be simplified to: 2x+33

2x - 10 =30 2x -10 = 30 +10 +10 2x = 40 /2 /2 x = 20

30-2=28 so 2x=28 28 divided by 2=14, so x is 14

x+30 = 3x-50 x-3x = -50-30 -2x = -80 x = 40

2x + 30 = 4x + 22 Subtracting 2x from both sides, 30 = 2x + 22 Subtracting 22 from both sides, 8 = 2x Dividing both sides by 2, 4 = x x = 4

2x + 30 = 4x + 10 Subtracting 2x from each side, 30 = 2x + 10 Subtracting 10 from both sides 20 = 2x Dividing both sides by 2 10 = x x = 10

Subtract 2x from each side: 30 = 10x - 50;Add 50 to each side: 80 = 10xDivide each side by 10: 8 = x

Set up the equation and solve: 8x + 8 = 2x +38 (subtract 2x and 8 from both sides of the equation) 6x = 30 (divide both sides of the equation by 6) x = 5

30+12x = 6(5+2x)

If: 3x+20 = 2x-10 Then: x = -30

basically: simplify. -6 (5-2x)=54 (-30)-2x=-324 -30x=-162 x=-132

There's nothing to solve, it's simply an expression.

2x + 6 - 6x = 30= 6 - 4x = 30= -4x = 24= 4x = -24= x = -6

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.

y = 5 - 2x so 4x + 6(5 - 2x) = -2 ie 4x + 30 - 12x = -2 Subtract 30 from each side: 4x - 12x = -32 ie -8x = -32 so x = 4 and y = -3

2X+5Y+30=0 So you subtract 30 from each side. 2X+5Y+30-30=0-30. So you know 2X+5Y=-30. now there are many different possibilities for X and Y unless there is a specification. here are some possibilities=X=0,Y=6 or X=A5,Y=0 or X=5,Y=4

if you want to "solve" this equation, you need an equals sign somehwere! For example, if the problem was 2x - 52=5 then you could solve. You add 52 (or 25) to both sides so the equation becomes 2x = 30. Then you divide both sides by 2 to get x=15

2x + 3y = 12 x = 1.45, so 2 * 1.45 + 3y = 12 2.9 + 3y = 12 3y = 12 - 2.9 = 9.1 y = 9.1/3 = 3.0333... or 91/30 or 3 1/30.

-x + 9 - 2x = -21 combine like terms -x and -2x isolate -3x by subtracting 9 from both sides divide both sides by -3 -3x + 9 = -21 - 9 - 9 -3x = -30 x = 10

X=30 2x+2x+x+30=180; All of the angles in a triangle always add up to 180. Therefore 5x+30=180; subtract 30 to be 5x by itself. Therefore 5x=150; divide by 5 to find x. Therefore X=30 2(30)+2(30)+30+30=180

It does not help you.

If the question is in the context of angles, then x + 20 + x + 10 = 90 ie 2x + 30 = 90 or 2x = 60 which gives x = 30

x=8

(x2 + 2x + 15)/(x - 3) = x + 5 + 30/(x - 3) where x â‰ 3
