What is the value of X

Mathematics
1 answer:
Alexus [3.1K]3 years ago
6 0

Answer:

30

Step-by-step explanation:

Use part/whole proportions. 10/25 (15 + 10) = 12/x. Multiply 12 times 25 (300) = 10x (10 times x). 300 = 10x, isolate x by dividing both sides by 10 and you get 30 = x.

The sum of two integers is 6 and the difference between the numbers is 40. Find the numbers
nevsk [136]


Set up a system of equations.

X+y=6
Y-x =40

Substitution method.

Y=6-x

(6-x)-x =40
6-2x=40
-2x=34
X= -17

Plug it back into the equation.
-17+y=6
Y=33

(-17,33) is one of the possible answers.
