Good job developers! The key thing we are supposed to demonstrate here (and in similar "infinite solutions" problems) is that we realize that in a problem with infinitely many solutions, both sides of the equation must be the same when simplified, so that any value for x will give the same result. When solving linear equations, the most important thing to remember is that the equation will remain equivalent to the original equation. \(2k(x 2) = x 2\)In the equation above, \(k\) is a constant. So it's gonna be ax plus x. Well that's going to be true for any x. The equation has one solution because the equation is true for all values of \(x\). If 16 7w = w + 14 6w, what is the value of w 1?
