+ 10x + 13 = 4

Answer 1

`x = -1`

Explanation:

Equation:
`1+10x+13=4`

Step 1: Balance both parts of the equation.

`1+10x+13=4`

`(10x)+(1+13)=4`

`10x+14=4`

`10x+14=4`

Step 2: Reduce 14 from both parts of the equation.

`10x+14-14=4-14`

`10x= -10`

Step 3: Split both sides by 10, because
`\mathrn {10x = -10}`.

`(10x)/(10) = (-10)/(10)`

`10 / -10 = -1`

Therefore, x = -1.
