Answer:
.
Step-by-step explanation:
5x + 3y = 26 (times 6) 30x + 18y = 156
6x + 7y = 21 (times 5) 30x + 35y = 105
.
30x + 18y = 156
<u>30x + 35y = 105 </u> <u> </u>
-17y = 51
y = -3
.
Substitute the value of y to one of equations
6x + 7y = 21
6x + 7(-3) = 21
6x - 21 = 21
6x = 21 + 21
6x = 42
x = 7
Your equation would be like this:
y=11x+300
because 11 depends on 'X" how many miles he walks and then just add 300 to that because that is the fixed amount

800*.035 = 28 This is interest per year.
28 * 7 = $196 Total interest earned for seven years
Total money in account is $996
To solve q+(-9)=12 we do the following.
q+(-9)=12
+9 +9
q=21
Giving us are end answer of q=21.
