2x + x + 4 +2x = x + 20 5x + 4 = x + 20 5x - x = 20 - 4 4x = 16 x = 4

4x =20x=20/4x=5

4x-5y+20 = 0 -5y = -4x-20 y = 4/5x+4 which is now in slope intercept form

4(x + y - 5) = 0

4x - 20 = -44x = 16x = 4

Only if 4 dollars plus 4 dollars equals 8 dollars.And if you had another 4x, you'd have a dozen-x.

-20 = -4x +6 add 20 to both sides 0 = -4x +26 4x = 26 x = 26/4 = 6.5

-8x + 4 = -4x; (-8+4)x = -4; x = 1.

Parallel, the slope of the second equation is 4

Slope-line form is: y = -4(x/5 + 1)

x-intercept of y equals -4x plus 4 y = -4x + 4 0 = -4x + 4 -4 = -4x 1 = x So 1 is the x-intercept

You need to organise your question properly. 3x+2y=4 4x + 3y= 7? Is 4 4x = 44x or 4-4x or 4+4x How can there be 2 equal signs in 1 equation?

-4x = 20x = 20/-4x = -5

4x = 20 x = 5 (divide both sides by 4)

4

y=4

4(1-4x+7y)

2y = 4x + 4y = 2x + 2

If: 3x+5 = 4x+1 Then: x = 4

-4x + 6 = 26 Subtract 6 from both sides: -4x = 20 Divide both sides by -4: x = 20/-4 Solve for x: x = -5

x(x+4) equals x2 plus 4x

That equals 1/4.

The value of x is 2

9x+3-25 = 4x-2 5x = 20 x = 4

(4x-20) = 119
