Solve the following equations and find the values of x and y.
2x + 4y + 2 = 0 x + 3y + 1 = 0
Explanation:
2x + 4y + 2 = 0
x =
Substituting in x + 3y + 1 = 0,
If ax + by + c = 0, and dx + ey + f = 0 has to be solved using the substitution method, then from ax + by + c = 0, x =
Explanation: From ax + by + c = 0, x =
