Henry showed all the steps he took to solve the equation. (picture) sammy tried to verify the solution by substituting x=5 back into the original equation. it did not result in a true statement. which explains why henry’s solution is incorrect? step 1 is wrong because the distributive property of equality was used incorrectly. step 2 is wrong because the addition property of equality was used incorrectly. step 3 is wrong because the subtraction property of equality was used incorrectly. step 4 is wrong because the division property was used incorrectly.
