Question 1089952: James has two planks of wood. One of them is 16m less than 3 times the length of the other one . The total length of the two planks is 8 metres long.
If one of the planks of wood has a length of x metres long. Write an algebraic expression of the other plank Answer by ikleyn(52921) (Show Source):
Second plank: x meters long.
First plank: 3x - 16 meters long.
Both together are x + (3x-16) = 4x - 16.
Your equation is
4x - 16 = 8.
Your solution is
4x = 8 + 16 = 24 ====> x = 6.
Answer. Second plank is 3 m. First plank is 3x-16 = 3*6 - 16 = 2m.
