Ok so, let's solve your equation step-by-step, Step 1: Cross-multiply.27=3x2x−52*(2x−5)=3x*(7)4x−10=21x
Step 2: Subtract 21x from both sides.4x−10−21x=21x−21x−17x−10=0
Step 3: Add 10 to both sides.−17x−10+10=0+10−17x=10
Step 4: Divide both sides by -17.−17x−17=10−17x=−1017
Answer:x=−1017
Hope this helps and mark as brainliest! BTW nice question!

2/7 = 3x / (2x - 5)
this is a proportion so we cross multiply
(7)(3x) = (2)(2x - 5)
21x = 4x - 10
21x - 4x = -10
17x = -10
x = -10/17
this is a proportion so we cross multiply
(7)(3x) = (2)(2x - 5)
21x = 4x - 10
21x - 4x = -10
17x = -10
x = -10/17
