A1 would be the first y value, which is 3 and d is the ratio ( distance between each y value) which is 3 ( add 3 to the y value to get the next one)
The answer is a1= 2, d = 3
X=-7 divide both side by 3. Any expression divided by itself equals 1. Dividing a positive and a negative equals a negative. Calculate the quotation. Then you get X=-7
3x-5=13
Move -5 to the right side and change the sign
3x=13+5
Add 13+5
3x=18
Divide both sides by 3
X=6
