How do you solve #(4-f)/5=(f+1)/3#?

Answer 1

#f = 7/8#

This problem is simply a matter of rearranging terms and is solved as such: #(4-f)/5=(f+1)/3# #3(4-f) = 5(f+1)# #12-3f = 5f + 5# #12 - 5 = 5f + 3f# #7 = 8f# #f = 7/8#

To solve the equation (4-f)/5=(f+1)/3, cross multiply to eliminate the fractions, then solve for f. First, multiply both sides by 5 and 3 to get rid of the denominators: (4-f) * 3 = (f+1) * 5 Next, distribute and simplify: 12 - 3f = 5f + 5 Now, isolate the variable f: 12 - 5 = 5f + 3f 7 = 8f Finally, solve for f: f = 7/8
