11. solve v + 6 = 5v - 2 for v <==
12. 60x + 10 = 40x + 70
20x = 60
x = 3............same at 3 hrs.....190 miles <==
12. 60x + 10 = 40x + 70
20x = 60
x = 3............same at 3 hrs.....190 miles <==
11. since both equations = m, then make both equations = each other so you would have v+6 = 5v-2 and solve for v
12. just like in 11 make both equations = each other and solve for x
60x+10 =40x+70
60x = 40x+60
20x =60
x = 60/20 = 3 hours
now use that as x to calculate miles
60(3) +10 = 190
3 hours, 190 miles
