Answer:
(3, -3)
Step-by-step explanation:
To solve for a system of equations, use substitution.
First, solve for one variable in an equation.
2x - 3y = 15
Add 3y to both sides.
2x = 3y + 15
Divide both sides by 2 to get x by itself.
x = 1.5y + 7.5
Put this in the other equation.
5x + 2y = 9
Substitute the variable.
5(1.5y + 7.5) + 2y = 9
Distribute the 5 inside the 1.5y + 7.5.
7.5y + 37.5 + 2y = 9
Combine like terms.
9.5y + 37.5 = 9
Subtract 37.5 from both sides.
9.5y = -28.5
Divide both sides by 9.5.
y = -3.
Now take this value and put it in the other equation to get your x.
2x - 3y = 15
Substitute variable.
2x - 3(-3) = 15
Multiply.
2x + 9 = 15
Subtract 9 from both sides.
2x = 6
Divide both sides by 2.
x = 3.
Your pair is (3, -3).
Answer;dj ghost 1 hunnit
Step-by-step explanation:a hunnit
If the interst rate is 2% per year and she paid it back after 3 years , it means she paid an extra 6% of $2000 just in interests.
Now we just need to find how much 6% is and add to 2000.
to discover the value of 6% of 2000 we can divide it by 100 ( to find 1%) and then multiply it by 6 ( to find 6%) :
2000 ÷ 100 = 20
1% = 20
6% = 20 × 6
6% = 120
Now add 120 to 2000 to find out how much she paid in total:
2000 + 120 = 2120
Awnser : She paid the total of $2120 over 3 years
I hope you understood my brief explanation. And please consider marking this awnser as Branliest. Thank you ! :)
