Question 153699
You can separate the A and the x like this:
{{{Ax+3 = 2A}}} Subtract 2A from both sides.
{{{Ax-2A+3 = 0}}} Subtract 3 from both sides.
{{{Ax-2A = -3}}} Now factor the A on the left side.
{{{A(x-2) = -3}}} Finally, divide both sides by (x-2)
{{{A = -3/(x-2)}}}
Now if you really wanted to solve for x, then:::
{{{Ax+3 = 2A}}} Subtract 3 from both sides.
{{{Ax = 2A-3}}} Divide both sides by A
{{{x = (2A-3)/A}}}
