<h3>Linear equations</h3>
Linear equation are expression that has a leading degree of 1.
Let the price of each DVD be x such that if Grace bought a television for $329 and some DVDs for $5.75 each and spent a total of $363.50, ten;
329 + 5.75x = 363.5
Subtract 329 from both sides
329 + 5.75x - 329 = 363.5 - 329
5.75x = 34.5
x = 34.5/5.75
x = 6
This shows that the total number of DVDs that she bough is 6

yes u no
Step-by-step explanation:
Hello,
Let's 2k-2,2k,2k+2 the 3 even integers
2k-2+(2k)+(2k+2)=30+2k-2
==>4k=28
==>k=7
The 3 integers ared 2*7-2=12, 2*7=14,2*7+2=16
12+14+16=42=30+12
