Answer:
(1,2)
Step-by-step explanation:
We arbitrarily set out to eliminate x and then find y.
Keep 4x-3y=18 as is, but multiply 2x+y=4 by -2. We get -4x - 2y = -8.
Combine:
4x - 3y = 18
-4x - 2y = -8
-------------------
-5y = -10
Solving for y, we get y = 2.
To find x, substitute y = 2 into either of the given equations. If we choose the second equation, we get 2x + (2) = 4, so that 2x = 2 and x = 1.
The solution is (1, 2).

Line r is twice line m. i.e. r = 2s which means that they are linearly dependent.
Therefore there are infinitely many solution to the given set of equations.
I’m attaching a photo. For each of these, start by multiplying both sides of the inequality by what’s in the denominator.
When drawing of the number lines, the circle is filled in if the any quality has an “equal than.” Otherwise, the circle is left open.
When dividing by a negative number, the direction of the inequality flips. Greater than becomes less than, and vice-versa.
Neither side of town due to the fact that none of the ratios are under 8%.
