Hope this helps!
8+2(12-5)
here we solve the bracket part first
8+2(7)
Now multiplying 2*7
8+14
=22
Answer 8+2(12-5)=22
Answer:
x = 68°
explanation:
As its a right angle triangle, it has 90° angle.
solve:
x + 22° = 90°
x = 90° - 22°
x = 68°
Methods for solving a system of equations:
- elimination
- substitution
- augmented matrix
Ranks of method ( number one being the most preferred method)
1) elimination
2) substitution
3) augmented matrix
Elimination is my preferred method because it is simple and easy to work out and hard to get wrong.
Augmented matrix is my least preferred method because it is easy to get wrong and it requires complex steps to solve a simple equation.
Hope this helps ;)
