27 I think ou this is weird what exactly is the subject
Steps to solve:
1 + 4x = -5 + 7x
~Subtract 1 to both sides
4x = -6 + 7x
~Subtract 7x to both sides
-3x = -6
~Divide -3 to both sides
x = 2
Best of Luck!
Answer:
L = w + 5
P = 2(L+w) = 42
L + w = 21
w+5 + w = 21
2w + 5 = 21
2w = 16
w = 8 ft
L = w+5 = 13 ft.
Rectangle is 13 ft by 8 ft
Area = 13(8) = 104 ft2
Check: P = 2(L+w) = 2(13+8) = 2(21) = 42 ft
Answer:

Step-by-step explanation:
Multiply both sides by 3/4.
(3/4)(4/3)x = (3/4)8
x = 6
