Find two numbers whose sum equals 299 , and in which one numbe is one less than 3 times the value of the other number .

Step-by-step explanation:

suppose the numbers are x and y. Then

-------------(1)

One number say y is one less than 3 times the value of the other number say x

-------------(2)

Substitute y=3x-1 in equation (1)

Now put x=75 in equation (2)

answer: r there any options?

step-by-step explanation:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
