X-y=7
so you have to rewrite the equation in the form of mx+b=y
so ... x-y=7
-x -x
-y=7-x then simplify
-y(-y)=-(7-x) multiply both sides by -1
y=-7+x
which is the same y= x-7
y=x+-7

Find MA:
MA = 67.2-32 = 35.2
Now set up a ratio:
35.2/67.2 = x/81.9
Cross multiply:
67.2x = 2882.88
Divide both sides by 67.2:
X = 42.9
