Answer:
Step-by-step explanation:
Perimeter = 84 cm
2*(length + width) = 84
2* (2x - 8 + x - 2) = 84
2*(2x + x - 8 - 2) = 84 {bring like terms together}
2*(3x - 10) = 84 {add/ subtract like terms}
Divide both sides by 2
3x - 10 = 42
3x - 10 +10 = 42 + 10 {add 10 to both sides}
3x = 52
Divide by 3,
x= 17 1/3
Length = 2x - 8
Hey there!
-11b + 7 = 40
- SUBTRACT by 7 on each of your sides.
-11b + 7 - 7 = 40 - 7
Cancel out: 7 - 7 because that gives you 0
Keep: 40 - 7 because it helps us solve for our answer
40 - 7 = 33
11b/-11 = 33/-11
Cancel out: -11b/-11 because it equals 1
Keep: 33/-11 because it gives you -3
33/-11 = 33 ÷ -11 = 3
<h3>
<u>b</u><u> = -3 </u></h3>
Good luck on your assignment and enjoy your day!

Answer:
One solution.
Step-by-step explanation:
3(x + 9) = 2x + 54
3x + 27 = 2x + 54
3x + 27 - 2x = 2x + 54 - 2x
x + 27 = 54
x + 27 - 27 = 54 - 27
x = 27
