Louisa states that the solution to the equation 1/4x - 3 = 3/8x + 4 is x = 56. she verifies her solution using the steps below.
equation: 1/4x - 3 = 3/8x + 4
step 1: 1/4(56) - 3 = 3/8(56) + 4
step 2: 14 - 3 = 21 + 4
step 3: 11 = 25
which statement most accurately describes louisa’s error?
a. louisa made an error when determining the original solution of x = 56.
b. louisa made an error when substituting the solution in for x.
c. louisa made an error when multiplying 56 by 1/4 and by 3/8
d. louisa made an error when adding or subtracting.
