Answer 1

Question: One number is one less than a second number. Twice the first is 4 more than 5 times the second. Find the numbers.

Answer:

The numbers are -3 and -2

Step-by-step explanation:

Given

Let the numbers be a and b

From the first statement:

$a = b - 1$

From the second:

$2a = 4 + 5b$

Required

Find a and b

Substitute b - 1 for a in the second equation

$2(b-1) = 4 + 5b$

$2b-2 = 4 + 5b$

Collect like terms

$2b- 5b = 2+ 4$

$-3b = 6$

$b =-2$

Recall that:

$a = b - 1$

$a = -2 - 1$

$a =- 3$
