What is the solution to
3x + 7 = x + 13 ?

x = 1.5

or

x =

Step-by-step explanation:

First, move +7 to the other side of equation on the answer side and change it to it's absolute (in this case I mean negative) value:

3x + x = 13 - 7

Next, Simplify the equation:

4x = 6

Finally, Celebrate! You just (hopefully) learned how to solve this!

x = 1.5

or

x =

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!
