<span>5 × 23 × 2 = 5 × 2 × 23 = 10 × 23 = 230</span>
You could make an equivalent fraction by multiplying both numbers by 2.
The solution to the system of inequalities is (-3.375, 1.75)
<h3>How to graph the inequalities?</h3>
The system of inequalities is given as:
3y > 2x+12
2x+y < -5
Next, we plot the graph of the system using a graphing tool
From the graph, both inequalities intersect at
(-3.375, 1.75)
Hence, the solution to the system of inequalities is (-3.375, 1.75)

Answer:
9 and 3
Step-by-step explanation:
10/15=6/(2x-9)
90=10(2x-9)
9=2x-9
x=9
18-8=10
10/(4x+3)=8/12
120=8(4x+3)
30=8x+6
x=3
