Question

Solve for B 25+ 7/9=74

Answer 1

To solve this equation, we need to follow the next steps:

1. Subtract 25 to both sides of the equation:

`25-25+(7)/(9)b=74-25`
`(7)/(9)b=49`

We obtained this result doing the corresponding operations (25 - 25 = 0), and (74 - 25 = 49).

2. Multiply by 9/7 to both sides of the equation:

`(9)/(7)\cdot(7)/(9)b=(9)/(7)\cdot49\Rightarrow(9)/(9)\cdot(7)/(7)b=9\cdot(49)/(7)\Rightarrow b=9\cdot7\Rightarrow b=63`

To check if the solution for this equation is b = 63, we can substitute this val
