Force = mass x acceleration
1. -2g = 1.75 -4
-g = -2.25/2
g = 1.12
X=5 , x=3 - just plug in 2 and 3 into x and the lines will make it positive instead of negative
Remember you can do anything to an eqautoin as long as you do oit to both sides
-5x=15
try to get 1x by itself
remember
(ax)/a=x when a=a
so
-5x=15
get x
divide both sides by -5
remember to flip sign
(-5x)/(-5)=15/(-5)
x=-3
answer is first one
x=-3
