Answer:
Step-by-step explanation:
Isolate the term of x and y from one side of the equation.
<h3>y=-15x-5 and 11x+y=-17</h3>First, you have to substitute.
Then, you solve.
Add by 5 from both sides.
-4x-5+5=-17+5
Solve.
-17+5=-12
-4x=-12
Divide by -4 from both sides.
-4x/-4=-12/-4
Solve.
-12/-4=3
<u>x=3</u>
y=-15*3-5
Solve.
PEMDAS stands for:
- Parenthesis
- Exponents
- Multiply
- Divide
- Add
- Subtract
15*3=45
Rewrite the problem down.
y=-45-5
Solve.
<u>y=-50</u>
<u>Therefore, the correct answer is y=-50 and x=3.</u>
