Part A: Explain how you will solve this pair of equations using substitution. Show all the steps and write the solution. (5 points) Part B: On a graph, what point will the lines representing the two equations intersect? Explain your answer. (5 points)

y = 16x + 4
y = 25x − 23

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

i think the amount would be $140.62
