-4x+3 = 23+6x -4x-6x = 23-3 -10x = 20 x = -2

6X + 3 = 2X + 19Subtract 3 from each side:6X = 2X +16Subtract 2X:4X = 16Divide by 4X = 4

4x-3+6x+3 4x+6x=10x -3+3=0 10x is the answer!

If: 6x-6 = 4x Then: x = 3

2x+9=6x-3 Therefore 4x=12 -->x=3

6x + 3 = 2x + 5 4x = 2 x=1/2

If: 6x-6 = 4x Then: x = 3

It is an equation and the value of x is 4

2x+9=6x-3 Therefore 4x=12 -->x=3

6x + 8 = 6 6x = -2 x = -2/6 x = -1/3

6x + 14 = 20 + 4x ------ Combine like terms (subtract 4x and 14 from both sides). 2x = 6 --------------------- Divide by 2. x = 3

2x + 4x + 3 = 6x + 3

Multiply the first by 3 and the second by -2

4x+6x=30 is the same as: 10x=30 so we divide by 10 and get: x=3 (I do not see how this relates to calculus, but O.K.)
