Solve 2 x plus 3 equals 9x?

Answer 1

2x + 3 = 9x

Subtract '2x' from both sides

3 = 7x

Divide both sides by '7'

7x/7 = 3/7

x = 3/7

Answer 2

2x + 3 = 9x is a fairly simple linear equation (i.e., when graphed, it will be a straight line).

First, you want to isolate the x term on one side of the equation. To do this, you must take 2x and subtract it from both sides. Here is the result:

7x = 3.

Now, you want to completely isolate x itself, without any coefficient (in this case 7). Because 7 is being multiplied to x, you must divide 7 from both sides. Keep in mind that whenever solving an equation, whatever you do to change it must be done to both sides. Here is the result:

x = 3/7.

If you wish, you may use a calculator to divide 3 by 7, or you can just leave it as a fraction.
