Question

The result of adding 15 to x and dividing the answer by 4 is the same as taking x from 80. 1. express the statement as an algebraic equation
2. find the value of x.

Answer 1

Answer:

61

Step-by-step explanation:

algebraic equation of this statement =

$\frac{(x + 15)}{4} = 80 - x$

now finding the value of x

=

$\frac{(x + 15)}{4} = 80 - x \\ = (x + 15) = 4(80 - x) \\ x + 15 = 320 - 4x \\ = x + 4x = 320 - 15 \\ 5x = 305 \\ x = \frac{305}{5} = 61$
