Question

If 13-3x is 5x less than 9, what is the value of 2x?

Answer 1

Convert the written statement into an equation: 'is' refers to the equal sign, 'less than' is subtraction.


`\sf 13-3x=9-5x`

Now solve for 'x', afterwards we can find the value of 2x. Add '5x' to both sides:


`\sf 13+2x=9`

Subtract 13 to both sides:


`\sf 2x=-4`

Divide 2 to both sides:


`\sf x=-2`

Now we know what 'x' is, just plug that into 2x to find what 2x is:


`\sf 2x\rightarrow 2(-2)\rightarrow \boxed{\sf -4}`

Answer 2

Hey there!

An equation to represent this is 13 - 3x = 9 - 5x.

We can directly solve for 2x if we take these steps:

First, add 5x to each side.
13 + 2x = 9

Then subtract 13 from each side.
2x = -4

Usually, we would then divide by 2 to find the value of x, but in this case we are solving for 2x, so we do not need to take any more steps.

The value of 2x is -4.

Hope this helps!
