The work of a student trying to solve the equation 4(2x − 1) = 11 + 3x + 5 is shown below: step 1: 4(2x − 1) = 11 + 3x + 5 step 2: 8x − 4 = 16 + 3x step 3: 8x + 3x = 16 − 4 step 4: 11x = 24 step 5: x = 2.18 in which step did the student first make an error and what is the correct step?
a. step 2: 8x − 1 = 16 + 3x
b. step 2: 8x − 8 = 6 + 3x
c. step 3: 8x − 3x = 16 + 4
d. step 3: 8x + 3x = 16 − 8

Iam trying to solve a linear equation for the shoe size of someone 84" tall taking into consideration example 1 is 69" tall with a shoe size of 9 and example 2 is 72 inches tall with a shoe size of 11. i understand that the equation should be y=mx+b and that on the graph the answer is (3,2) but i just don't understand how to create the equation to solve for 84-inches and 60-inches tall questions. after two days, i need .

(a) (8%) compute the probability of an even integer among the 100 integers 1! , 2! , 3! , until 100! (here n! is n factorial or n*(n-1)*(n-2) *… 1) (b) (16%) compute the probability of an even integer among the 100 integers: 1, 1+2, 1+2+3, 1+2+3+4, …., 1+2+3+… + 99, and 1+2+3+… + 100
