Solve x-3y=-6 and 2x-y=3 using equal value method

x = 3

y = 3

Step-by-step explanation:

To solve x - 3y = -6 and 2x - y = 3 using equal value method, express othe same variable from each equation.

1st equation:

2nd equation:

Equate the right sides of these expressions:

Multiply by 2:

Substitute it into the first expression:

Hi there! supplementary angles are angles that add up to a straight angle, or 180 degrees. to figure out the angle that is supplementary to an angle that is 77 degrees, all we need to do is to subtract 77 from 180.work: 180 - 77 = 103supplementary angle = 103 degreeshope this : )if there's anything else that i can you with, let me know!
