Which equation is part of solving the system by substitution?
x+y=11
4 + 11) - 3y = 8
4(11-yje - 3y=8
40 - 11) - 372 = 8

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
