$ The sum of twe numbers is 42. Their difference is 16.

tresset_1 [31]

Answer:

x = 29

y = 13

Step-by-step explanation:

Write 2 equations:

x + y = 42

x - y = 16

Isolate x in the first equation:

x = 42 - y

Substitute this in for x in the second equation:

42 - y - y = 16

42 - 2y = 16

solve for y:

-2y = -26

y = 13

Plug in 13 for y in either equation:

x + 13 = 42

Solve for x:

x = 29

The sum of a number and 5 times a second number is represented by the equation a+5b=19 . The sum of half of the first number and

TiliK225 [7]

Here you have a system of 2 equations and 2 unknowns. An easy way to solve this type is to isolate one of the variables.

12a + 2b = 8
2b = 8 - 12a
b =
$b = \frac{8 - 12a }{2}$
b = 4 - 6a

Now plug 4 - 6a into equation 1 to solve for a.

a + 5(4 - 6a) = 19

a + 20 - 30a = 19

-29a = -1

a = 1/29 (answer)

Now plug a into the equation for b

b= 4 - 6(1/29)

b= 110/29 (answer)
