Question

7x + 3.350 = 91

can some help me with this equation ​

Answer 1

x=12.5 to the nearest tenth

Explanation:

We want to solve for x in

`7x + 3.350 = 91`

This is a linear equation in x.

We subtract 3.350 from both sides to get:

`7x = 91 - 3.350`

We simplify on the right to get:

`7x = 87.65`

Divide both sides by 7 to get:

`x = (87.65)/(7)`

This implies that

`x = 12.5`
