Answer:

answer is x = 8

Step-by-step explanation:

If it says add 3 you subtract it to the 43 and that turns into 40, divide both sides by 5 and you get x = 8 :)

Answer:

x=8

Step-by-step explanation:

Im not sure what your question means,but you need to find x.

5x+3=43

You subtract 3 on both sides

leaving your equation to be

5x=40

Now divide the 5

and you will get x=8

Check:

5(8)+3=43

40+3=43

43=43

Use a system of equations to solve this problem.

X = amount of seeds.

y = amount of dried fruits.

we know the snack mix contains both, and we know is 10oz, thus x + y = 10, whatever ounces "x" and "y" are.

how much is it for "x" ounces if each one costs $1.5?  well is just 1.5*x or 1.5x.

how much is it for "y" ounces if each one costs $2.5?  well is just 2.5*x or 2.5x.

the mix contains 10 ounces, each of which costs $2.2 each, how much will it be then for 10 oz?  well, is just 10 * 2.2, or $22.

since the whole 10 oz snack mix costs 22 bucks, then 1.5x + 2.5y = 22.

\bf \begin{cases}
x+y=10\implies \boxed{y}=10-x\\
1.5x+2.5y=22\\
-------------\\
1.5x+2.5\left( \boxed{10-x} \right)=22
\end{cases}
\\\\\\
1.5x+25-2.5x=22\implies -x+25=22\implies 3=x

how many ounces of dried fruit is there anyway?  well, y = 10 - x.
