Answer:
x=-33/5 y=29/5
Step-by-step explanation:
Let's solve your system by substitution.
3x+y=−14;2x−y=−19
Solve
3x+y=−14 for y:
3x+y=−14
3x+y+−3x=−14+−3x(Add-3x to both sides)
y=−3x−14
Next is to substitute −3x−14 in for y 2x−y=−19:
2x−y=−19
2x−(−3x−14)=−19
5x+14=−19(Simplify both sides of the equation)
5x+14+−14=−19+−14(Add -14 to both sides)
5x=−33 Dived both sides by 5
5x/5=-33/3
x=−33/5 since you can't dived and a fraction is another form of division you keep it this way.
Step: Substitute -33/5 for x in y=−3x−14:
y=−3x−14
y=−3(-33/5)-14
y=29/5
(Simplify both sides of the equation)(since you can't dived and a fraction is another form of division you keep it this way.)
So
x=-33/5 and y=29/5
Pls mark brailest this took me a long time to write out lol. Hope this truly helps! Send a heart if so, so I can keep spreading the help!
6. 6 3 1/4 inch pieces of ribbon can be cut from 19 1/2 inches of ribbon
So the sides ML and MN are exactly the same. Your equation would look something like this...
3x = x + 10
You first subtract x from both sides to isolate the variable.
2x = 10
Divide 2 from both sides.
x = 5
5 is the length of MN.
I hope this helps love! :)
The amount of last year sales is $ 528400
<em><u>Solution:</u></em>
Let "x" be the amount of last year sales
Given that,
The total sales at Office Products this year are $713,340, which is 35% more than last year’s sales
Therefore,
This year sales = 35 % more than last year sales
This year sales = 35 % of last year sales + last year sales
713340 = 35 % of x + x
Thus amount of last year sales is $ 528400
-5(x – 3) = x + 27
multiply the bracket by -5
(-5)(x)=-5x
(-5)(-3)=15
-5x+15=x+27
Move +15 to the other side. Sign changes from +15 to -15.
-5x+15-15=x+27-15
-5x=x+27-15
-5x=x+12
Move +x to the other side. Sign changes from +x to -x.
-5x-x=x-x+12
-6x=12
Divide both sides by -6
-6x/-6=12/-6
Answer: x=-2
