Question 105358
Solve by addtion:
2x-y = 1
-2x+3y = 5 Add the two equations and the x's dissapear leaving you with:
----------
2y = 6 Divide both sides by 2.
y = 3 Now substitute this value of y into either one of the two original equations and solve it for x.
2x-y = 1
2x-3 = 1 Add 3 to both sides.
2x = 4 Divide both sides by 2.
x = 2
Check: Substitute x = 2 and y = 3 into the two given equations.
1st equation:
2x-y = 1
2(2)-3 = 1
4-3 = 1
1 = 1
2nd equation:
-2x+3y = 5
-2(2)+3(3) = 5
-4+9 = 5
5 = 5
