Answer:

Step-by-step explanation:

vector e is (-1,5),f is (3,-4),g is (2,1)

2i+j=x(-i+5j)+y(3i-4j)

2=-x+3y (multiply by 5)

10=-5x+15y

1=5x-4y

add

11=11y

y=1

2=-x+3(1)

x=3-2=1

2i+j=1(-i+5j)+1(3i-4j)

This Is very simple.

30m + 50 = 20m + 100

This is the new equation needed to solve for m.
first we must isolate "m".

30m + 50 = 20m + 100
        - 50             - 50

30m = 20m + 50
-20m   -20m

10m = 50

divide both sides by 10 to isolate "m".

m = 5

hope this helps!
