 Question 226682: I need help with figuring out how to do a problem like this: Solve the following systems of equations using any method. Check each solution, if possible: a. -2x+3y=1 2x+6y=2 solution: Solve the second equation for x (you could solve for y - it doesn't matter). 2x + 6 y = 2 becomes x = -3y +1 Now, substitute -3y +1 for x in the first equation. This gives the equation -2(-3y +1)+3y = 1 6y -2 +3y =1 9y -2 =1 9y= 3 y=3/9 or y = 1/3 Now, substitute 1/3 for y in either equation and solve for x. (We use the second equation below.) 2x + 6(1/3) = 2 2x + 2 = 2 2x = 2- 2 2x =0 , x = 0 The solution is the ordered pair, (0, 1/3). now you can check where you see x just replace with 0 , and where see y just replace it with (1/3).. good luck Click here to see answer by 3788(5)
