Answer:
9 + 8 + 12 = 29
Step-by-step explanation:
1.) 5x + 10y = 15 => x + 2y = 3 => 3x + 6y = 9
2.) -9x - 12y = 6 => 9x + 12y = -6 => 3x + 4y = -2
3.) -2x + 4y = -5 => 2x - 4y = 5 => 4x - 8y = 10
2212 ÷ 79 = 28
221 ÷ 79 = 2 with remainder of 63, bring down 2 and it becomes 632
632 ÷ 79 = 8 with no remainder
so you got 28
Hope that helps you. :-)
