Answer:
x = 11
Step-by-step explanation:
3(2x-4) = 5x-1
6x + (-12) = 5x + (-1)
add -12 to both sides, subtract 5x from both sides. Simplify.
x=11
Your intention with the wording "consecutive integers of 12 feet" is not clear. Shown are triangles with sides 12 and 13 (a nice Pythagorean triple) as well as 11 and 12.
