Question

soo how i do this its hard to simplify it

Answer 1

Answer:

v = 3

w = -3

I used a calculator called m.a.t.h.w.a.y :)

Answer 2

Answer:

1.

$\longrightarrow\sf \: - 8v + 4(v + 5) = 8 \\ \longrightarrow\sf \: - 8v + 4v + 20 = 8 \: \\ \longrightarrow\sf \: - 4v = 8 - 20 \: \: \: \: \: \: \: \: \: \: \: \\ \longrightarrow\sf \: - v = \frac{-12}{4} = - 3\: \: \: \: \: \: \: \: \: \: \: \: \\ \longrightarrow\sf \: \: v = 3 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

2.

$\longrightarrow\sf \:6(w + 2) - 8w = 18 \\ \longrightarrow\sf \:6w + 12 - 8w = 18 \: \\ \longrightarrow\sf \: - 2w = 18 - 12 \: \: \: \: \: \: \: \: \\ \longrightarrow\sf \: - w = \frac{6}{2} = 3 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \longrightarrow\sf \:w = - 3 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

Hope it helps you mate :)
