Step-by-step explanation:
yeah that one
Answer:
20 people
Step-by-step explanation:
There hope you have a good day
3x+4y=5
2x+3y=
-2(3x+4y)=5(-2)
3(2x+3y)=4(3)
-6x-8y=(-10)
6x+9y=12
Add the equations
-6x-8y=(-10)
+ 6x+9y=12
-----------------
0x+y=2
y=2
Substitue y into an equation
6x+9(2)=12
6x+18=12
6x=-6
x = -1
y = 2
Hmmmmm i just did this assignment the other day let me check
Answer:
x=1, y=-1. (1, -1).
Step-by-step explanation:
2x+y=1
3x-y=4
-------------
y=3x-4
2x+3x-4=1
5x-4=1
5x=1+4
5x=5
x=5/5
x=1
y=3(1)-4=3-4=-1
