What would the equation be

Question

The San Diego public library has 44 fewer branches than the Chicago public library define a variable and Wright an equation for the number of branches of the San Diego public library Chicago has 79 branches

Answer 1

If we let x represent the number of branches in the San Diego library, then we can say that x plus 44 would equal the number in Chicago's library (which is 79)

The equation would be :

x + 44 = 79

You can solve this equation using inverse operation. Subtract 44 from both sides of the equation:

x + 44 - 44 = 79 - 44

x = 35 branches in the San Diego library

You could also write 79 - x = 44 and solve and get the same result.
