Solve by elimination:
4x + 4y = 4

x=−y+1

Step-by-step explanation:

Let's solve for x.

4x+4y=4

Step 1: Add -4y to both sides.

4x+4y+−4y=4+−4y

4x=−4y+4

Step 2: Divide both sides by 4.

4x        =    −4y+4

4          =        4

x=−y+1

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

answer: 1000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
