Determine the number of slack variables and name them. Then use the slackvariables to convert each constraint into a linear equation.How many and which slack variables should be assigned?st)ciasA. There are three slack variables named x_1, x_2, s_1B. There are five slack variables named x_1, x 2, s_1, s_2, s_3.c. There are three slack variables named s_1, s_2, s_3.D. There are two slack variables named s_1, s_21Assume the first equation using a slack variable is 5x? - x_2+s? = 164. What isthe second equation after the slack variable is introduced?OA. 15x? +6x2 +5? +5? =201OB. 15x, +6x? +S? =201OC. 15x? +6x2 +52 = 201Maximize z= 8x? + 3x_2subject to:with5X, -X_2's 16415x? + 6x 2 s 20110x 1 + x 2X?20? 340x 220
