Answer:
Step-by-step explanation:
Answer:
This is an example of equation with two unknowns. Andre bought x pounds of zucchini and y pounds of broccoli and we also know that there was 10 pounds of veggies in total. So, we can write:
$1.5 • x + $2 • y = $17
x + y = 10
From the second equation we can say that:
y = 10 - x
We can now enter this value of y into the first equation:
1.5 • x + 2 • (10-x) = 17
1.5 • x + 20 - 2 • x = 17
1.5x - 2x = 17 - 20
-0.5x = -3
0.5x = 3
x = 6
If x=6, then y=10-6, which is 4.
That means that Andre bought 6 pounds of zucchini and 4 pounds of broccoli.
