What is the solution to the system of equations? Use the substitution method.
Juli2301 [7.4K]
Y -3x = 7  from this result y = 7 +3x what value of y we need substituting in place of y inside second equation and will get 
21 +9x = 3y 

21 +9x = 3(7 +3x)
21 +9x = 21 +9x
        0 = 0

so this mean that there are an infinite number solutions so choice B. is right
