Question

If the output number y is -52 (y=5x-2) what is the input number? SHOW WORK

Answer 1

the input number is -10

Explanation:

output is always y

input is always x

so instead of y, put -52

-52=5x-2 add 2 to each side to ger 5x by itself

-50=5x divide both sides by 5 to get x by itself

-10=x

x is the input so the input is -10
