Answer:

b= 352/3

or b= 117.33

Explanation:

262-3x+85=-5

-3x+(262+85)=-5

simplify the arithmetic

-3x+347=-5

Group all constants on the right side of the equation

-3x+347=-5

Subtract from both sides:

-3x+347-347=-5-347

Simplify the arithmetic:

-3x=-5-347

-3x=-352

isolate the x

-3x=-352

Divide both sides by -3

-3x/-3}=-352/-3}

Cancel out the negatives

3x/3}=-352/-3

Simplify the fraction

x= -352/-3

Cancel out the negatives

x=352/3
