Step-by-step explanation:
Here we are asked to solve a pair of linear inequalities.
In order to do so , we are first required to plot the two lines with inequalities taking into considerations.
Hence let us plot
x+2y=-4 and 5x+2y=4
let us first plot x+2y=-4
let us plot a table for the same for two random values of x and putting them into above equation
x y
0 -2
2 -3
Let us now plot these points and join the line .
Let us check whether (0,0) satisfies the in equation or not
0+2(0)≤-4
0≤-4
Which is not true , Hence we shade the portion divided by our line which does not contain (0,0)
Now let us plot the second line 5x+2y=4
let us plot a table for the same for two random values of x and putting them into above equation
x y
0 2
1 -0.5
Let us now plot these points and join the line .
Let us check whether (0,0) satisfies the in equation or not
5(0)+2(0)≤4
0≤4
Which is true , Hence we shade the portion divided by our line which does contain (0,0)
Please refer to the image attached with this answer.
now the commonly shaded area as shown in the image will be our solution to the above pair of in equations.
You can multiply each fraction on both top and bottom so that they have 24 as the denominator. The equation becomes 
subtract 16/24 to both sides and you get
now subtract 20/24 from both sides and
<u />
multiply 24 on both sides
-26=21m
and divide by 21 on both sides
m=-26/21 or -1.24
subtract 16/24 to both sides and you get
now subtract 20/24 from both sides and
multiply 24 on both sides
-26=21m
and divide by 21 on both sides
m=-26/21 or -1.24
