You want to first use the distributive property to distribute out the 3 and 7.3x + 5 = 37x - 14 = 5I think all you have to do is solve for x with one of these equations, and see if the answer works on the other equation.3x = -2x = -2/3Now plug it into the other equation.7(-2/3)-14 = 5-14/3 - 14 = 5-14/3 - 42/3 = 5-56/3 = 5um....it seems like the answer does not work....is this a system of equations or what?
