3y = 5xy = x + 23y = 5x3(x + 2) = 5x3x + 6 = 5x3x - 3x + 6 = 5x - 3x6 = 2x6/2 = 2x/23 = xy = x + 2 = 3 + 2 = 5Thus, the solution of the set is (3, 5)Check:
4y - 6y + 9y = -2Combine like terms on the left side:7y = -2Divide each side by 7:y = -2/7The solution set is: { -2/7 }
What is the solution set for the equations x-y=2 and -x+y=2
a= 2, b = 3 (or vice-versa)
This equation is not possible. Two plus three plus four plus five does not equal 287. The system has no solution.
