Answer:
C)Add the equations in step 1 to eliminate one variable
Step-by-step explanation:
Given is a system of equations as
Step I is to multiply I equation by 3 and ii equation by 4
Step 2 will be to add both equations arrived in step I so that y will be eliminated.
We get 26x=104
x=4
and y =9
Thus correct answer is C)

Given:
In a right triangle, the measure of one acute angle is 12 more than twice the measure of the other acute angle.
To find:
The measures of the 2 acute angles of the triangle.
Solution:
Let x be the measure of one acute angle. Then the measure of another acute is (2x+12).
According to the angle sum property, the sum of all interior angles of a triangle is 180 degrees. So,
Divide both sides by 3.
The measure of one acute angle is 26 degrees. So, the measure of another acute angle is:
Therefore, the measures of two acute angles are 26° and 64° respectively.
