Answer :

To solve the equation [tex]\(2(h + 3.5) = -11\)[/tex], let's proceed step-by-step:

1. Expand the left side of the equation:
Distribute the 2 to both [tex]\(h\)[/tex] and 3.5.
[tex]\[ 2h + 2 \cdot 3.5 = -11 \][/tex]
Simplifying the multiplication:
[tex]\[ 2h + 7 = -11 \][/tex]

2. Isolate the term with [tex]\(h\)[/tex]:
Subtract 7 from both sides of the equation to move the constant term to the right side.
[tex]\[ 2h + 7 - 7 = -11 - 7 \][/tex]
Simplifying both sides:
[tex]\[ 2h = -18 \][/tex]

3. Solve for [tex]\(h\)[/tex]:
Divide both sides by 2 to isolate [tex]\(h\)[/tex].
[tex]\[ \frac{2h}{2} = \frac{-18}{2} \][/tex]
Simplifying the division:
[tex]\[ h = -9 \][/tex]

So, the solution to the equation [tex]\(2(h + 3.5) = -11\)[/tex] is:
[tex]\[ h = -9 \][/tex]
