Malik collects rare stamps and has a total of 212 stamps. Solve the system of equations.

ICE Princess25 [194]

Using the two given equations:

x - y = 34

x +y = 212

Rewrite the first one in terms of x:

x = 34 + y

Now replace x in the 2nd equation:

34 + y + y = 212

Simplify:

34 +2y = 212

Subtract 34 from both sides:

2y = 178

Divide both sides by 2:

y = 178/2

y = 89

Now replace y in an equation to solve for x:

x + 89 = 212

x = 212-89

x = 123

He has 123 domestic stamps and 89 foreign stamps.

Can someone who will answer this question please answer this

Doss [256]

Answer:

CBD=63

Step-by-step explanation:

Since ABD is the total angle which contains CBD and ABC, ABC+CBD=96. With this, you can set up an equation.

6x+27+7x-9=96

13x+18=96

13x=78

x=6

6x+27=6(6)+27=36+27=63 degrees. Hope this helps!
