12 + 3x = 412 - 12 + 3x = 4 - 123x = -83x/3 = -8/3x = -8/3x = -(2 2/3)

If: 3x+6 = 12 Then: x = 2

3x = -12 so x = -4

simplify it, 7x-12=x+2+2x-3x 7x=2+12+3x-3x 7x=14 x=2

5x - 10 = 3x + 2 5x - 3x = 2 + 10 2x = 12 x = 12/2 x = 6

3x + 2 = -10 3x = -12 x = -4

y = 12. It's the transitive property. y = 12 = 3x.

3x - 2y = 12 2y + 12 = 3x 2y = 3x - 12 y = 3x/2 - 6 Gradient = 3/2 Y-intercept = -6

"2 over 3x equals 4" is an equation in a single variable, x.2/(3x) = 4 => 3x/2 = 1/4 => 3x = 2/4 = 1/2 => x = 1/6.

5x - 10 = 3x + 2 5x - 3x = 2 + 10 2x = 12 x = 12/2 x = 6

3x=3x-12-x**20=-12-x**2x**2=-12 (not possible w/ real numbers)x=i(12)**0.5=2i(3)**0.52x**2=3x2(-12)!=3(2i(3)**0.5)Equations do not equateEquation is wrong

3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
