Use Elimination Method.

anonymous · Answer

for the second one:
3(x+1)=-2(x-1)-4
3x+3=-2x+2-4
3x+3=-2x-2
3x=-2x-5
5x=-5
5x/5=-5/5
x=-1

Thank you! @juliax

anonymous · Answer

you're welcome :) im trying to work out the first one ;3

anonymous · Answer

i came to an answer but im honestly not sure it's right, i got $$\sqrt{32/30}=x $$

anonymous · Answer

can you help me with a problem when your done satellite?

anonymous · Answer

$$\frac{4}{5}x+\frac{4}{3}=2x$$ multiply both sides by 15  and get 
$$12x+16=30x$$ then solve for $x$

phi · Answer

sat has the right idea, but his arithmetic is rusty.

do what he said, multiply both sides by 15,  but notice (4/3) * 15 is not 16
