The solution to the system of equations using substitution is given by:
x = 4 and y = 2.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
For this problem, the equations are given by:
From the second equation, we have that:
x = -2y.
Replacing in the first equation, we have that:
3(-2y) + 0.5y = 11
-5.5y = 11.
5.5y = -11
y = -11/5.5
y = -2.
Then the solution for x is:
x = -2y = -2(-2) = 4.
The solution to the system of equations using substitution is given by:
x = 4 and y = 2.

I just need points honestly sorry have a good one thank you
6 flowers
x=weeks
4x divided by 2
4(3)= 12 then divided by 2,
=6
Step-by-step Answer:
What is the solution to the system of equations?
y = –3x – 2 ..............(1)
5x + 2y = 15..............(2)
Substitute (1) in (2) to give
5x + 2(-3x-2) = 15
5x-6x-4 = 15
-x-4=15
solve for x:
-4-15 = x
x=-19
Now substitute x=-19 into equation (1)
y = -3x-2 = 57-2 = 55
Therefore the solution is (-19, 55)
