Question

v-w=-5
v+2w=4

Use linear combinations to solve the system of linear equations.

Answer 1

What does the v-w=-5 stand for

Answer 2

idk

Answer 3

if i dont know then i cant solve it, i think

Answer 4

What does it say in the book

Answer 5

solve by substitution method for systems of equations:
v-w=-5
v+2w=4

v=-5+w
(-5+w)+2w=4

-5+3w=4
3w=9
w=3

v-(3)=-5
v=-2


w=3
v=-2
