Answer:

x = 9 and  y = -13

Step-by-step explanation:

7x + y =50.... eq 1

4x + y =23....eq 2

Subtract eq 2 from eq 1

7x + y = 50

-

4x + y = 23

This becomes;

7x - 4x + y - y= 50 -23

3x = 27

Divide both sides by the coefficient of x; 3

x = 9

Slot in the value of x in eq 1

7 (9) + y = 50

63 + y = 50

Subtract 63 from both sides

63 - 63 + y = 50 - 63

y = -13

The measure of an angle is seventy-one times the measure of a supplementary angle. What is the measure of each angle?
steposvetlana [31]

Let the smallest angle = x

Then the larger one = 71x

Supplementary angles are always equal to 180o

x + 71x = 180o Add the left side

72x = 180 Divide by 72

x = 180/72

x = 2.5

The smallest angle = 2.5 degrees

The largest angle = 2.5 * 71

The largest angle= 177.5 degrees.
