The second of two numbers is 8 less than twice the first number. What are the two numbers?

so the two numbers can be represented as x and y
so x is first and y is second
y=2(x)-8
so y=2x-8
IF THEY ARE CONSECUTIVE If they are consecutive numbers then x+1=y subtitute x+1=2x-8 subtract x from both sides 1=x-8 add 8 to both sides and get 9=x put it into the equation and get y=2(9)-8 y=18-8 y=10 so x=9 y=10 IF X AND Y ARE CONSECUTIVE INTEGERS (1,2,3,4 not 2.3 or 1,3,5,8)

x → t h e f i rs t n u mb er y → t h e seco n d n u mb er y = 2 ⋅ x − 8 f or e x am pl e : x = − 2 ⇒ y = 2 ⋅ ( − 2 ) − 8 = − 4 − 8 = − 12 x = 0 ⇒ y = 2 ⋅ 0 − 8 = 0 − 8 = − 8 x = 7 ⇒ y = 2 ⋅ 7 − 8 = 14 − 8 = 6

The second number can be expressed as y = 2 x − 8 . By choosing different values for the first number x , one can find corresponding pairs of values for y . For example, if x = 10 , then y = 12 ; if x = 0 , then y = − 8 .
