I believe you must subtract 99-60=39. Hope this helps.
Make it into slope intercept form which is y=mx+b
subtract x ffrom both sides
2y=-5-x
divide by 2
y=-1/2x-5/2
y=mx+b
m=slope
b=y intercept or where the line passes through the y-axis
now one way is to graph points by subsituting
if x is 0 then y=-5//2
if x=1 then y=-3
if x=-5 then y=0
another way is to find out where the line passes though the y and x axis or the y and x intecepts respectively
the y intercept is when x=0
the x intecept is when y=0
so set each to zero and solve
if x=0
y=-1/2(0)-5/2
y=-5/2
the line passes throught the y axis at -5/2, plot the point (0,-5/2) on the y axis
then set y to zero
0=-1/2x-5/2
add 5/2 to both sides
5/2=-1/2x
multiply -1
-5/2=1/2x
multiply by 2
-5=x
therefor the line passes through tthe x axis at (-5,0)
then draw the line between the 2 points
here is the graph

you can use the distributive property
assume a 1 in front of the prenthasees
93+1(68+7)
distribute
93+68+7
use communtative property to move around
93+7+68
add
100+68
168
