Question

Find the value of $(4a + 3b)^{20202020}$
given that $ax + 4 = 3x - b$ has more than one solution

Answer 1

Welcome to MSE. $$ax+4=3x-b\\ax-3x=-b-4\\x(a-3)=-(b+4)$$when this equation has more than 1 solution ? ..... when both sides get zero.
$$x\times 0=0$$ has more than one solution

can you take over?
