y= -4x-7 y=3x 3x= -4x-7 3x+4x=7 7x=7 x=1

-4

10

6x-7 = 3x+5 6x = 3x+12 (subtracting -7) 3x=12 (subtracting 3x) x=4 (dividing by 3)

-2X ? 14- 3x - 7 I am assuming you left something out so I put the question mark in. If it is -2X + 14 - 3x - 7 -Combine like terms -2x - 3x + 14 - 7 -5x + 7 DONE If it is -2X - 14 - 3x - 7 -Combine like terms -2X - 3X - 14 - 7 -5X - 21 DONE

3x = 7-4x 3x+4x = 7 7x = 7 x = 1

if 3x+7 = 3 then 3x = 3-7 3x = -4 then, x = -4/3

eq: 3x+5=7 =3x=7-5 =3x=2 =x=2/3

3x + 4= 7 3x= 7-4 3x/3 = 3/3 x=1

3x - 7 = 2 3x = 9 x = 3

3x+7=4x-73x=(-)7+4x-4x(-)1x=(-)7________(-)1x=7add (-3x) to each side of equation3x +7 = 4x-3x +3x +7 = 4x -3x0 +7= 1x7=x

3x = 7 - 4x 3x + 4x = 7 - 4x + 4x 7x = 7 7x/7 = 7/7 x = 1

The 7 is contant in 3x + 7, and the 3x term is variable depending on the value of x.
