Answer:
x= -6
v= 1
v= 2
Step-by-step explanation:
-3= x+7-4, combine like terms by subtracting seven from four
-3= x+3, subtract three from both sides
-6= x
8v-3+3v= 8, combine like terms by adding 8v and 3v
11v-3= 8, add three to both sides
11v= 11, divide both sides by 11
v=1
-v+3v=4, combine like terms by adding -v and -3v
2v= 4, divide both sides by 2
v= 2

Answer:
Barney 145 3 Days 310 Miles
Mary 250 5 Days 600 Miles
A) 3 D + 310 M = 145
B) 5 D + 600 M = 250
Multiplying A) by -5/3
A) -5 D - 516.6666M = -241.66666666
B) 5D + 600M = 250
Adding A) and B)
83.3333 M = 8.3333333333
M = .10 per mile
3 D = 114
