Someone me with math! will give brainliest to first person who

solve each system by substitution.
1. -5x-8y=9
y= -3.

2. y= -3x
-6x-2y=3

3. 6x+5y=10
y=-8x+2

4.6x+2y= -6
y= -3x -3

you!

Scenario: a rectangular plot of ground is 5 meters longer than it is wide. its area is 20,000 square meters. question: what equation will you find the dimensions? note: let w represent the width. options: w(w+5)=20,000 w^2=20,000+5 (w(w+5))/2=20,000 w+2(w+5)=20,000
