If we add 51 and 17 (51 + 17), we'd get 68 for an answer. The number 51 is 50 + 1, and the number 17 is 10 + 7, taking the units digits, 1 + 7 equals 8, and 50 + 10 equals 60. Further, 8 plus 60 is 68, so the sum of 51 and 17 is 68.
2x+6y = 24 5x-2y = 9 Divide all terms in the top equation by 2: x+3y = 12 => x = 12-3y Substitute x = 12-3y into the bottom equation: 5(12-3y)-2y = 9 60-15y-2y = 9 -15y-2y = 9-60 -17y = -51 y = 3 Substitute the value of y into the original equations to find the value of x: Answer: x = 3 and y = 3

14y - 51 = 187 + 4ySubtract 4y from each side:10y - 51 = 187Add 51 to each side:10y = 238Divide each side by 10:y = 23.8
yes.W= 7

Let me see:1) x + y + z = 7 y = 7 - x- z2) 2x + 3y- z = -23) -x + 3z = 36 x = 3z - 36Subst. 3) into 2):2(3z-36)+3y -z = -2Subst 1) into 3):2(3z-36) +3(7-x-z) - z = -2Subst 3) into 2) again:6z-64 + 3(7-(3z-36) - z) -z = -2z= 67/7Subst answer into 3) -x + 3(67/7) = 36x = -51/7Subst answers into 1):-51/7 + y + 67/7 = 7y = 33/7therefore x = -51/7, y = 33/7, z = 67/7
