Question

10×a number added to 5is same as 9times the nunber is what​

Answer 1

Negative 5

Explanation:

• Start by subtracting 5 from both sides, this is because it is the coefficient on the left side.

`10x+5-5=9x-5`

• Next, simplify by subtracting 5. Note that you can't subtract a singular whole number from a term, basically a number with a variable next to it.

`10x+5-5\\= 10x+\left(5-5\right)\\= 5-5\\=0\\=10x+0\\=10x`

--------------

`9x-5\\= 9x-5`

• Third, identify the simplified equation.

→
`10x=9x-5`

• Fourth, subtract by the term 9x. You always subtract by the term/leading term on the right side at this point in an inequality or algebraic equation. Note: Assume x is 1 as a placeholder until you find x's real value.

`10x-9x=9x-5-9x`

`10x - 9x\\= 1x\\= 1 * x\\= 1`

`9x-5-9x\\=9x\left(-5\right)-9x\\= 9x - 9x\\= 0 - \left(-5\right)\\= -5\\x = -5`

Hope this helps!
