let n = "a number"
:
write an equation for exactly what it says
:
If 8 is added to 7 times a number and the sum is divided by 3, the result is the same as if then number is multipled by 5 and 6 is added to the product.
%287n+%2B+8%29%2F3 = 5n + 6
get rid of the denominator, mult both sides by 3
7n + 8 = 3(5n+ 6)
7n + 8 = 15n + 18
7n - 15n = 18 - 8
-8n = 10
n = 10%2F%28-8%29
n = -1.25
:
Let's see if that works in the given statement
If 8 is added to 7 times a number and the sum is divided by 3, the result is the same as if then number is multiplied by 5 and 6 is added to the product.
%287%28-1.25%29+%2B+8%29%2F3 = 5(-1.25) + 6
%28-8.75%2B+8%29%2F3 = -6.25 + 6
%28-.75%29%2F3 = -.25; confirms our solution of n = -1.25
