Solve the system of equations y= -x+3 and 2x+2y=6 a) there are no solutions b) the solution is (2, -1) c) there are infinitely many solutions d) the solution is (-1, 3)

c) there are infinitely many solutions

Add x to the first equation to put it in standard form:

... x + y = 3

Divide the second equation by the common factor of all terms, 2, to put it in standard form:

... x + y = 3

These two equations describe the same line. Every point on the line is a solution to both equations, so there are infinitely many solutions. (We say these equations are "dependent.")

it depends on the weather. because i have flown to seattle when it was pouring down rain and there was one time i flew to ohio when it was snowing hard. whats your situation.

step-by-step explanation:

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9
