System #3, where x=6
System #1, where x=4
System #7, where x=3
System #5, where x=2
System #2, where x=1
Step-by-step explanation:
System #1: x=4
To solve, start by isolating your first equation for y.
Now, plug this value of y into your second equation.
System #2: x=1
Isolate your second equation for y.
Plug this value of y into your first equation.
System #3: x=6
Isolate your first equation for y.
Plug this value of y into your second equation.
System #4: all real numbers (not included in your diagram)
Plug your value of y into your second equation.
<em>all real numbers are solutions</em>
System #5: x=2
Isolate your second equation for y.
Plug in your value of y to your first equation.
System #6: no solution (not included in your diagram)
Isolate your first equation for y.
Plug your value of y into your second equation.
<em>no solution</em>
System #7: x=3
Plug your value of y into your second equation.

Answer:
The left side 5
The bottom 10
The slanted side 11
Step-by-step explanation:
To find the perimeter of the triangle, add up the side lengths
x+ 2x+1 + x+5 = 26
Combine like terms
4x+6 = 26
Subtract 6
4x+6-6 =26-6
4x=20
Divide by 4
4x/4 = 20/4
x=4
The left side x = 5
The bottom x+5 = 5+5 = 10
The slanted side = 2x+1 = 2*1 +1 = 10+1 =11
