If you would like to solve the system of equations x + y = 3 and 2x - y = 6, you can do this using the following steps:
<span>x + y = 3 ... y = 3 - x
2x - y = 6
</span>_________
<span>2x - y = 6
</span>2x - (3 - x) = 6
2x - 3 + x = 6
3x = 6 + 3
3x = 9 /3
x = 9/3
x = 3
<span>y = 3 - x = 3 - 3 = 0
</span>
The correct result would be x = 3.
35% because 35% of 80 is 28
Answer:
1) E and F
Step-by-step explanation:
So width is x
legth Is 3x+3
Perimeter is
3x+3+3x+3+x+x
Now simplify
8x+6
Now go through each choice that equals 8x+6
Only e and f
4x - 12
You can get this by switch the f(x) and the x and then solving for the new f(x)
