X=29
There is always a total of 180 degrees in a triangle. Let’s represent this mathematically.
180=35+52+3(x+2)
We can subtract the 35 and the 52 from both sides.
93=3(x+2)
Now, distribute.
93=3x+6
And subtract the 6.
87=3x
Finally, divide both sides by 3.
29=x

Step-by-step explanation:
( x-2y=12)5
5x-10y=60
- 5x+3y=-44
____________
13y=-104
y=-104/13
6.25% of $42,000 = $2,625
$42,000 + $2,625 = $44,625
Answer:
x= 1
y= 3
Step-by-step explanation:
21(-2+y) +7y = 42
-42 +28y+42
28y = 42+42
28y= 84
divide both sides y= 3
x= -2+3 x=1
x= + (3-2) = 1
42=42
10=10
