How many solutions does this system of equations have? Use either the substitution method or the elimination method. −2x + 4y = 4−2x + 4y = 4 x − 2y = 6x − 2y = 6 exactly one solution no solution infinitely many solutions
-2x+4y=4 Equation 1 x-2y=6 Equation 2 Solving by substitution method. Isolate x from equation 2. x=2y+6 Substitute value of x in equation 1 -2(2y+6)+4y=4 -4y-12+4y=4 -12=4 -16=0 Which is false.
