Answer 1

Mindy wants to solve the following system using the elimination method:

y = x – 4
y = 2x – 3

What number should the equation y = x – 4 be multiplied by to eliminate x? (4 points)



–1
–2
–4
–6

Answer 2

hey @shadow2239

Answer 3

you want to eliminate x from this equation, y = x – 4
when you throw it in this equation, y = 2x – 3

so make them match
2y = 2x - 8
y = 2x - 3

now the x's match, and will eliminate

Answer 4

-2

Answer 5

You have to multiply the entire equation by -2 so that the x's cancel, hence eliminated which gives you an equation of only y.
