I need help with this question please & thank you

For the equation below, x is the input and y is the output. y = -4x + 3 if the input is -8, then the output is

With this question substitute t=3 and t=5 to determine if the two expressions are equivalent. 4(t + 3) 4t+12 which statements are true? check all that apply. a. the value of both expressions when t =5 is 32. b. the two expressions are not equivalent. c. the value of both expressions when t=3 is 15. d. the value of both expressions when t=5 is 23. e. the two expressions are equivalent. f. the value of both expressions when t=3 is 24.

Find the value of x. give reasons to justify your solutions! c ∈ ae
