2x-y=3

use the substitution method

2(2)-y= 3

4-y= 3

move 4 to the other side

sign changes from +4 to -4

4-4-y= 3-4

-y= 3-4

-y=-1

mutiply both sides by -1 to get +y

(-1)(-y)= (-1)(-1)

y= (-1)(-1)

Answer: y= 1

An angle measures 10° less than the measure of its supplementary angle. What is the measure of each angle?​
spin [16.1K]

Answer:

The two angles are 85 and 95 degrees

Step-by-step explanation:

Supplementary angles add to 180

Let x be one angle

The supplement is 10 less,  ( x-10)

They add to 180

x+ ( x-10) = 180

2x -10 = 180

Add 10 to each side

2x-10+10 =180-10

2x= 190

Divide by 2

2x/2 =190/2

x=95

The other angle is 95-10 = 85

The two angles are 85 and 95 degrees

5*17=85

5*49=245


So, 17/49 or about 34.7%
