Please help and show step-by-step explanation, 45 points!!! Error Analysis Your friend used a graphing calculator to solve a system of linear equations, shown below. After using the TABLE feature, your friend says that the system has no solution. Explain what your friend did wrong. What is the solution of the system?

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.

Having a hard time understanding this question (see attachment).

50 will mark show all use the linear combination method to solve the system of equations. explain each step of your solution. if steps are not explained, you will not receive credit for that step. 2x+9y= -26 -3x-7y=13
