Let the smaller number be x .
Then the larger number = 3x
Their sum = -10
This can be written in an equation as :-
[tex]x + 3x = - 10[/tex]
[tex]4x = - 10[/tex]
[tex]x = \frac{ - 10}{ \: \: \: 4} [/tex]
[tex]x = - 2.5[/tex]
Which means :-
The value of the first number = -2.5
The value of the second number = -2.5 × 3 = -7.5
Therefore , the smaller of the two numbers is = -7.5
Answer:
let a + b = -10
where a = 3b
substitute a into the equation: a + b = -10
3b + b = -10
b = -10 / 4
b = -2.5
a = 3b
a = 3(-2.5)
a = -7.5
check:
a + b = -10
-7.5 + (-2.5) = 10
-10 = 10
