Hi I am new and need help with a pre-algebra question. The question is find the ordered pairs of y=4x-11 when 10 is the output. There are no answers to this equation.

hey @the_ocean_girl

the_ocean_girl · Answer

Okay so the output would be y, so substitute 10 in for y
10= 4x-11
Do you know how to solve this equation?

anonymous · Answer

that what i need help with

anonymous · Answer

srry meant that is what i need help with

the_ocean_girl · Answer

Okay so let's begin. In order to solve this, you need to do reverse order of operations

anonymous · Answer

ok so wouldn't it be like you said 10=4x-11

the_ocean_girl · Answer

Yep, now we have to solve for x, and once we do that, we'll have our ordered pair

anonymous · Answer

ok so can you help me on that? I know i am sounding really stupid right now

anonymous · Answer

Math is not my best subject right now

the_ocean_girl · Answer

It's fine! We all have our struggles in math! Okay so our goal is to get x alone, in order to do this, we need to first get rid of the 11. Do you add it or subtract it to get rid of 11?

anonymous · Answer

subtract

anonymous · Answer

if i am right

anonymous · Answer

@the_ocean_girl

the_ocean_girl · Answer

Since 11 is negative, you would need to cancel it out by adding 11

anonymous · Answer

ohh ok

anonymous · Answer

so -11+10?

anonymous · Answer

then when I add that then that would be -1 or if i do -11+4 then that answer would be -7.

anonymous · Answer

is that right @the_ocean_girl ?

the_ocean_girl · Answer

Sorry I was doing geometry. After adding 11, you would get 21= 4x. From there, you need to divide both sides by 4 to get your x value

anonymous · Answer

ohh i added -11

anonymous · Answer

21/4 is 5.25 or rounding it would be 5.3. Right?

anonymous · Answer

@the_ocean_girl

the_ocean_girl · Answer

No need to keep mentioning me! When you comment it'll notify me. But yes! You're right! As an ordered pair, it would be (5.3,10)

anonymous · Answer

oh ok so srry. I am totally new to this, I thought that is what I had to do.

anonymous · Answer

So if 5.3,10 is the first ordered pair what would the other pairs be?

the_ocean_girl · Answer

how many other ordered pairs is it expecting you to give?

anonymous · Answer

srry I was in a dba with a teacher. I solved the problem and got a 100% on the dba. Thank you so much ma'am.
