3x+y=7<br> 6x+4y=22<br> can somebody help me solve this problem?

Hey there!

$\boxed{x=1;y=4}$

$3x + y = 7 \\ \\ 
 6x + 4y = 22$

$y = -3x + 7 \\ \\ Plug \ this \ in \ for \ variable \ (y) \ in \ equation \ \\ \\ 

 6x + 4*(-3x+7) = 22 \\ \\ 
 -6x = -6 \\ \\ 6x=6 \ x+1 \\ \\ x=1 \ y=-3x+7 \\ \\ \boxed{y=-3(1)+7=4} \\ \\ \boxed{\boxed{x=1;y=4}}$

I hope this helps you!

Sam is moving bags of soil from a loading dock into a storeroom. The top soil weighs 40 pounds per bag and the mulch weighs 20 p

Levart [38]

Answer:

$40x+20y\leq 480$

Step-by-step explanation:

Givens

The top soil weighs 40 pounds per bag.
The mulch weighs 20 pounds per bag.
The cart can only carry up to 480 pounds.

Notice that the restriction is a maximum of 480 pounds, that means the inequality must include the sign $\leq$ .

Now, let's call $x$ the top soil and $y$ the mulch, the inequality that represents this problem, would be

$40x+20y\leq 480$
