Question

add $14 and $6 to find the cost of 7 pounds of grapes and 2 pounds of strawberries on the left side of the equation. then, we can see if its equal to $20.
the equation is $2g + 3s = 20$. substitute $g = 7$ and $s = 2$: $2(7) + 3(2) \stackrel{?}{=} 20$. then $14 + 6 = 20$, and we need to fill in the box for the sum of 14 and 6 and check if it equals 20.

Explanation:

Step1: Calculate sum of 14 and 6

$14 + 6 = 20$

Step2: Compare to right-hand side

$20 \stackrel{?}{=} 20$

Answer:

20, and $20=20$, so the equation holds true.
