3x-4=12 Plus 4 both sides 3x-4+4=12+4 3x=16 divide 3 both sides 3x/3=16/3 x=16/3 x= 5.33

3x + 4 = 28Subtract 4 from each side:3x = 24Divide each side by 3:x = 8
3 x 3 x 3 x 3 = 81. 4^3= 64. So no, they are not equal.
if 3x+7 = 3 then 3x = 3-7 3x = -4 then, x = -4/3
3x-4=12 Plus 4 both sides 3x-4+4=12+4 3x=16 divide 3 both sides 3x/3=16/3 x=16/3 x= 5.33

x/3x + 4 = 4 1/3.

-3x + 4y = 12∴ 4y = 3x + 12∴ y = 3x/4 + 3So this is a line with a slope of 3/4, an x-intercept of {0, 3} and a y-intercept of {-4, 0}
3x + 4 = 28Subtract 4 from each side:3x = 24Divide each side by 3:x = 8
(x-4)(3x-2)/(x-4) is equivalent to 3x-2 except when x=4.
It depends on the value of x. -3 = 4 -3x 3x = 7 so x =7/3 If x < 7/3 then -3 is greater if x = 7/3 then -3 is the same if x > 7/3 then -3 is smaller.
3 x 3 x 3 x 3 = 81. 4^3= 64. So no, they are not equal.
4(3x+7) = 12x + 28
if 3x+7 = 3 then 3x = 3-7 3x = -4 then, x = -4/3
3x+3=0 -3 = -3 = 3x=-3 /3 /3 x= -1
