Using the elimination method how do i do 5x + 6y = 50 -x + 6y =26

y = 5 and x = 4

Step-by-step explanation:

You need to get the same number either in front of both x's or both y's.

As there is already a value the same for both y's, we can already subtract the two equations:

5x - -x = 6x

6y - 6y = 0

50 - 26 = 24

6x = 24

Divide both sides by 6 to find x:

6x ÷ 6 = x

24 ÷ 6 = 4

x = 4

Substitute this value into first equation:

5(4) + 6y = 50

20 + 6y = 50

Move the +20 over to the other side making it a -20:

6y = 50 - 20

6y = 30

Divide both sides by 6:

6y ÷ 6 = 7

30 ÷ 6 = 5

So y = 5

This means that y = 5 and x = 4

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

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
