3x+2=2x+8
x=6

3x+2 = 2x + 8; first subtract 2x from both sides
x+2=8; then subtract 2 from both sides
x=6

it often simplifies arithmetic

4x3=12

250-12=238

238/50=4.76

(x2 - 4)/4x = 12; x ≠ 0

x2 - 4 = 48x

x2 - 48x = 4

x2 - 48x + 242= 4 + 242

(x - 24)2 = 4 + 576

x - 24 = ±√580

x = 24 ± 2√145

Yes. One at y= pi/2 and y=-pi/2

1/(1-x2 )1/2

8x plus 4y equals 5 is 8x + 4y = 5.

2x+4y=8

4y=-2x+8

y=-2/4x+2

M=-2/4

B=2

B=Y Intercept

If: y = x-4 and y = x2+y2 = 8 then 2x2-8x+8 = 0 and the 3 ways of proof are:

1 Plot the given values on a graph and the line will touch the curve at one point

2 The discriminant of b2-4ac of 2x2-8x+8 must equal 0

3 Solving the equation gives x = 2 or x = 2 meaning the line is tangent to the curve

-7

Yes.

horizontal is side to side

vertical is up and down

9x2 + 7x = 2

9x2 + 7x - 2 = 0

9x2 + 9x - 2x - 2 = 0

9x(x + 1) - 2(x + 1) = 0

(9x - 2)(x + 1) = 0

x ∈ {-1, 2/9}

-4x + 6 = 26

Subtract 6 from both sides: -4x = 20

Divide both sides by -4: x = 20/-4

Solve for x: x = -5

17

2x+2=161-4x

6x+2=161

6x=159

x=26.5

See that? Add 4x to the other side, Subtract 2 from the other side, divide 159 by 6.

Done.

5x+12 = 4x-88

x = -100

y = 5x + 3

To graph this line, we need to find two points of it on a graph and draw a straight edge using them. Two easy-to-find points are the y- and x-intercepts. The y-intercept of any linear function in the form

y = mx + b

is simply b. Is this case, b = 3. So a point must be (0,3). For the x-intercept, set y = 0 and solve for x:

0 = 5x + 3

-3 = 5x

-3/5 = x.

So a second point (-3/5,0).

It is an equation and the value of x is 6.5

It depends on the material as well as the force of gravity.

Probably yes. Unfortunately, though, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to be certain.

Put x = 0. The equation is then y = 0 + 5 or y = 5

Mark the point (0,5).

Put y = 0. The equation then becomes 0 = x + 5 or x = -5

Mark the point (-5, 0)

Joint the two points and extend the line in both directions.
