Answer:
x= 8
y = 21
Step-by-step explanation:
27 + 3y = 90
3y = 90 -27
y = 63/3
y = 21
x+ 90 +8x+18 = 180. { linear pair}
9x +108 = 180
9x = 180-108
x= 72/9
x = 8
-2a²b + a² + 3ab² - b² + 2(a²b + 2ab)
Simplify the parenthesis first.
-2a²b + a² + 3ab² - b² + 2a²b + 4ab
Now, add like terms.
(-2a²b + 2a²b) + 3ab² + 4ab + a² + b²
Simplify.
3ab² + 4ab + a² + b²
That is the simplest it can be simplified.
