Best ResponseYou've already chosen the best response.07x=7 if x=1 then this equation is true, correct? if we add 3 to each side 7x+3=10 and x is still 1, the equation is still true just looks different

Best ResponseYou've already chosen the best response.0Now that we know this. we can substitute the x's for a y. This is called the substitution method. 3(y) + 2y = 25 Now solve for y
