So it can be written as 2x + 5 = 11, and x = 3
13x = 39 can replace 3x + 5y = 59 in the original system and still produce the same solution.
Answer:
Step-by-step explanation: Try to solve it urself by putting necessary formulas of algebra that are in your textbook. thankyou!!!!!
For this problem, you need to substitute 4 in for your variable t. the original equation is S(t) and the one you need is S(4) -- in other words, evaluate this equation when t = 4.
S(4) = 9(4) - 4
S(4) = 36 - 4
S(4) = 32 is your answer.
