x=first number
5x-1 = 2nd no.
5x-1-x=51
4x=52
x=13 is first number
64 is the second

Hello
Let y = one number
let x = second number
So x-y=51
x = 5y-1
Hence replace y = 5x -1 into the first equation giving us
5y-1 -y = 51
4y-1 = 51 so 4y = 52 and y = 13 x= 5*13-1 = 64
Hope This Helps!

If the numbers are A and B, then you're told A - B = 51 and that B = 5A - 1. You have two equations with two unknowns, so solve for A and B.

Setup:
X - 5X -1 = 51
Combine like terms:
-4X - 1 = 51
Get X on one side:
-4X = 52
Solve for X:
X = 52/-4
X equals first number:
X = 13
Solve for second number:
5(13) - 1 = ?
Answer 64
Summary:
The two numbers are 64 and 13.
Verify:
64-13 = 51 CORRECT!

Let x= the first number
5x-1=2nd number
since you are given with the difference= 51
5x-1-x=51
4x=52 (transpose it)
x=13
5x-1=64 (substitute it from the representative)
the 2 numbers are 13 and 64

Let x and y be the numbers; x is bigger
Statement 1: x-y=51
Statement 2: 5y-1=x
So 5y-1-y=51 and 4y=52
So y=13 and x=64

let the numbers be a(first) and b(second)
1) b - a = 51
2) b = 5a - 1
substituting 1 in 2
5a - 1 - a = 51
4a = 52
a = 13
b - a= 51
b - 13 = 51
b = 64

Let
x = be the 1st no.
5x-1 = be the 2nd no.
5x -1 -x = 51
4x = 52
x = 13
5x-1 = 64

-13, and 64 because
x (1st number)
5x-1 (2nd number)
x-5x-1=51
add like terms
-4x-1=51
+1 +1
-4x=52
Divide -4 into 52 you get -13 so:
x=-13
5x-1= 64
64-13=51

first figure out ur given
the difference of two numbers is 51
x-y=51
then see what they tell you
the second is 1 less than 5 times the first
y-1=5x
now solve for y
y=5x+1
now plug that into your equation
x-5x+1=51
so that you hav like variable and solve for x
x=-50/4 or -12.5
now plug that into the original equation
x-y=51
(-12.5)-y=51
y=-63.5
so your numbers are -12.5 and -63.5
