What is the solution of the system? Use either the substitution method or the elimination method. 4x + 2y = 104x + 2y = 10 x − y = 13x − y = 13
There is no solution.
(3.5, −1)
(6, −7)
(−7.5, 2)
4x+2y=10 Equation 1 x-y=13 Equation 2 Solving by substitution method. Isolate x from equation 2. x=y+13 Substitute value of x in equation 1 4(y+13)+2y=10 4y+52+2y=10 6y+52=10 6y=-42 y=-7 Now substitute value of y in x=y+13 x=-7+13 x=6
