Answer:
16 = 5x + 6
Explanation:
You spend $16 on 3 notebooks and x binders. Notebooks cost $2 each and binders cost $5 each.
From this, we can see that our total amount of money spent is $16. This goes on one side of the equation.
T = 16
You have bought 3 notebooks that cost $2 each. An equation would be
n = 2x with x the number of notebooks bought. Plug 3 into x.
n = 2(3)
n = $6
You spent $6 on notebooks.
Your overall equation will be:
T = 5b + n
T is the total amount of money spent, x is the number of binders purchased, and n is the total amount of money spent on notebooks only.
Plug in the values you know.
16 = 5x + 6
To solve for x, subtract both sides by 6.
16 - 6 = 5x + 6 - 6
10 = 5x
Isolate x further by dividing both sides by 5.
x = 2
You bought 2 binders.
Hope this helps!
