-4x + 8 = -4 -4x + 8 - 8 = -4 -8 -4x = -12 -4x/-4 = -12/-4 x = 3

x = -8, y = 10

X=5/12

3x + x + 8 = 204x + 8 = 204x = 12x = 3

x = 11/7 and y = 12/7

Add 12 to each side: 4x + 6x = 20 ie 10x = 20 so x = 2

5x-8 = x+125x-x = 8+124x = 20x=5

x=5

4x + 8 + 7x + 12 = 11x + 20

-6x-6 -or- -6(x+1)

X equals to 8

Simplify 4x + 3 = 2x + 8 2x = 5 x =2½

8-3x-x = 12 8-4x = 12 -4x = 12-8 -4x = 4 x = -1

4x+32=-4x+16x4x+32=12x-4x -4x32=8x/8 /84=x

4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3

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

x=3

4x+5=7x-8 the ansewr is 3.25

yes

8 + y = 4x8 + y - 4x = 4x - 4x 8 + y - 4x = 0 8 - 4x + y = 0

That equals 1/4.

Solving these simultaneous equations by the elimination method:- x = 1/8 and y = 23/12

8 + 4x - x = 8 3x = 8 - 8 x = 0

x = 2, y = 84x + 8y= 4(2) + 8(8)= 8 + 64= 72

8+4x
