Answer:

y = 3/8, x = 7/4

Step-by-step explanation:

x = 2y+1

-7(2y+1) - 2y = -13

-14y - 7 - 2y = -13

-16y - 7 = -13

-16y = -6

y = 3/8

Plug the value for y into one of the equations to solve for x

Good morning.

In level 4, the experience needed is:

$\mathsf{g(4) = 7\cdot3^{4-1}}\\ \\ \mathsf{g(4) = 7\cdot3^3 = 7\cdot27}\\ \\ \mathsf{g(4) = 189}$

In the hardest settings, the multiplier is:

$\mathsf{h(4) = 4\cdot 4}\\ \\ \mathsf{h(4) = 16}$

So, the adjusted experience points are: multiplier . base experience

$\mathsf{E(x) = h(x)g(x)}\\ \\ \mathsf{E(4) = h(4)g(4) = 16\cdot 189}\\ \\ \boxed{\mathsf{E(4) = 3024 \ points}}$
