Let the two numbers be x and y.

x + y = 86
+
x - y = 12
_________
2x + 0 = 98
__________


2x = 98

x = 98/2
 
x = 49


From    x + y = 86

49 + y = 86

y = 86 - 49

y = 37

The numbers are 49 and 37.

The sum of two numbers is 15. four times the smaller number is 60 less than twice the larger number. what is the larger number?
kirza4 [7]
X = smaller number, y = larger number
x + y = 15.....x = 15 - y
4x = 2y - 60

4(15 - y) = 2y - 60
60 - 4y = 2y - 60
60 + 60 = 2y + 4y
120 = 6y
120/6 = y
20 = y <==== larger number is 20

x + y = 15
x + 20 = 15
x = 15 - 20
x = - 5

Simplify 7 - 2(5 - 2x) -10x + 25 -4x - 3
Kisachek [45]

Hi,

Let's simplify this equation step-by-step.

7−2(5−2x)−10x+25−4x−3

Distribute:

=7+(−2)(5)+(−2)(−2x)+−10x+25+−4x+−3

=7+−10+4x+−10x+25+−4x+−3

Combine Like Terms:

=7+−10+4x+−10x+25+−4x+−3

=(4x+−10x+−4x)+(7+−10+25+−3)

=−10x+19

Answer:

=−10x+19

Have a great day!
