Solve for [tex]x[/tex].

[tex]9(x+1)=18[/tex]

Sagot :

Sure, let's solve the equation step-by-step:

1. Original Equation:
[tex]\[ 9(x + 1) = 18 \][/tex]

2. Distribute the 9 on the left side:
[tex]\[ 9 \cdot x + 9 \cdot 1 = 18 \][/tex]
[tex]\[ 9x + 9 = 18 \][/tex]

3. Isolate the term with the variable [tex]\(x\)[/tex]:
To do this, subtract 9 from both sides of the equation:
[tex]\[ 9x + 9 - 9 = 18 - 9 \][/tex]
Simplifying both sides, we get:
[tex]\[ 9x = 9 \][/tex]

4. Solve for [tex]\(x\)[/tex]:
Divide both sides of the equation by 9 to isolate [tex]\(x\)[/tex]:
[tex]\[ \frac{9x}{9} = \frac{9}{9} \][/tex]
Simplifying, we get:
[tex]\[ x = 1 \][/tex]

Thus, the solution to the equation [tex]\(9(x + 1) = 18\)[/tex] is:
[tex]\[ x = 1 \][/tex]
