What is x equal to? We would have to find the actual value to compare. No variable.
Answer:
- x = 12
- 3x+1 = 37°
- 10x-11 = 109°
- 3x-2 = 34°
Step-by-step explanation:
Perhaps you want to know the value of x or the measures of the angles?
__
Simplifying the given equation, you get ...
(16x -12)° = 180°
16x = 192 . . . . . . . divide by °, add 12
x = 12
(3x+1)° = (3·12+1)° = 37°
(10x-11)° = (10·12-11)° = 109°
(3x-2)° = (3·12-2)° = 34°
x is 12, and the angle measures are 37°, 109°, 34°.
it's 3/2 because it rises three and goes over two. hope this helps !!
Solutions
In Matrix we use initially based on systems of linear equations.The matrix method is similar to the method of Elimination as but is a lot cleaner than the elimination method.Solving systems of equations by Matrix Method involves expressing the system of equations in form of a matrix and then reducing that matrix into what is known as Row Echelon Form.<span>
Calculations
</span>⇒ <span>Rewrite the linear equations above as a matrix
</span>
⇒ Apply to Row₂ : Row₂ - 2 <span>Row₁
