Answer:

x=12.5 to the nearest tenth

Step-by-step explanation:

We want to solve for x in

[tex]7x + 3.350 = 91[/tex]

This is a linear equation in x.

We subtract 3.350 from both sides to get:

[tex]7x = 91 - 3.350[/tex]

We simplify on the right to get:

[tex]7x = 87.65[/tex]

Divide both sides by 7 to get:

[tex]x = \frac{87.65}{7} [/tex]

This implies that

[tex]x = 12.5[/tex]
