Answer:
x=18
Step-by-step explanation:
<u>Key skills needed: Arithmetic Sequences, Addition</u>
1) We have a sequence of 8,13,x
2) To find the number being added every time, we do 13-8. This is 5.
3) This means x would be 13+5
4) 13+5 is 18 so x is 18.
<em>Hope you understood and have a nice day!! :D</em>
-5x + 3(2x - 6) = -13
-5x + 6x - 18 = -13
x = 5 => y = 4
