Second one tell me if im wrong
Step-by-step explanation:
A1=8
A2=A1+5 plug 8 into A1 here. After getting the value, put into next equation. And repeat until you get A5
A3=A2+5
A4=A3+5
A5=A4+5
First you solve for y.
5x+ y= 12 so Y= 12-5x
And plug it into the next equation
3x- 3(12-5x) = 18
Distribute
3x-36+15x=18
Add 36 to both sides
3x+ 15x= 54
18x= 54 ... divide
x= 3
And you can plug in x to solve for Y
5(3) + y = 12
15+ y = 12 ...subtract 15 from both sides
y= -3
