2x-2x-7 = 9x-2x+3

-7 = 7x+3

Subtract 3 from each side

-7-3 = 7x+3-3

-10 = 7x

Divide each side by 7

-10/7 =7x/7

-10/7 =x

step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
