11x+9=7x+21 11x-7x=4 4x+9=21 21-9=12 4x=12 12 divided by 4= 3 x=3

3+3x+7x=13 3x+7x=10 10x=10 x=1

Subtract by 7x and divide by 2.

4x+9 = 7x+3 4x-7x = 3-9 -3x = -6 x = 2

7x + y + 3 = y7x + 3 = 07x = -3x = -3/7

7x + 8 = 11x + 3, solve for xsubtract 7x from both sides8 = 11x - 7x + 38 = 5x + 3subtract 3 from both sides5 = 5xdivide both sides by 51 = x.

7x+7=28x 28x-7x=7 21x=7 x=3

X = -3

Why not? The statement is trivially true, meaning it holds for all values of x.
