How do you solve #2f + 6 = 19#?

Answer 1

Abigail Allen

#f = frac{13}{2}#

First, subtract 6 from both sides of the equation to get: #2f = 13#

Then divide both sides of the equation by 2 to get: #f = frac{13}{2}#

#f=6.5#

Step 1: Subtract 6 from both sides. #2f+6=19# #2f=13#

Step 2: Divide both sides by 2. #(2f)/2=13/2# #f=6.5#

To solve the equation 2f + 6 = 19, you need to isolate the variable f.

First, subtract 6 from both sides to move the constant term to the other side of the equation: 2f + 6 - 6 = 19 - 6 2f = 13

Next, divide both sides by 2 to solve for f: 2f / 2 = 13 / 2 f = 6.5
