Answer:
[tex]x = -1[/tex]
Step-by-step explanation:
Equation: [tex]1+10x+13=4[/tex]
Step 1: Balance both parts of the equation.
[tex]1+10x+13=4[/tex]
[tex](10x)+(1+13)=4[/tex]
[tex]10x+14=4[/tex]
[tex]10x+14=4[/tex]
Step 2: Reduce 14 from both parts of the equation.
[tex]10x+14-14=4-14[/tex]
[tex]10x= -10[/tex]
Step 3: Split both sides by 10, because [tex]\mathrn {10x = -10}[/tex].
[tex]\frac{10x}{10} = \frac{-10}{10}[/tex]
[tex]10 / -10 = -1[/tex]
Therefore, x = -1.
