4 pounds of books because 60 oz only equals 3.75 pounds.
56/1 x 11/8 here is the equations now just multiply them
1 3/9 but if reduce to lowest term than 1 1/3
Answer:
(8 * x) + 2x = 60
8x + 2x = 60
10x = 60
/10 /10
x = 6
8 is a constant that is being multiplied by an unknown number which we will name x. It is then being added to two times the unknown number(x), so we multiply x by 2, which is 2x. The final product will be 60, so in the equation it'll then equal 60.
We consider "a number" to be a variable that withholds an unknown value, which is x (or any other variable you prefer).
