Bedmas (pedmas) Backwards

B - Brackets or parentheses
E - Exponents
D - Division
M - Multiplication
A - Addition
S - Subtraction

Explanation:

Bedmas is used when solving equations with multiple steps but when solving for the unknown it is used backwards

When solving for the unknown you want to isolate the variable and to do this you bring everything but the variable to the other side of the equal side.

First lets look at bedmas backwards, therefore subtraction and addition would be first

#c/3 **- 17.58** = -14.08#

The -17.58 is what we are going to bring first to the other side of the equal side and when doing thing it become Positive

A rule is when ever you bring something to the other side of the equal side it does the inverse operation

#c/3 = -14.08+17.58#
#c/3 = 3.5#

Then using bedmas backwards again we look at multiplication and subtraction.

#c/3 = 3.5#

Let's focus on #c/3# here the c is being divided by the three so when we bring it over to the other side the three will no longer divide but multiply

#c = 3.5*3#
#c = 10.5#

Therefore, C = 10.5
