Answer:
Step-by-step explanation:
Step One: We need to find a way to equate either the x terms of the y terms in each equation. ...
Step Two: Take equation b) from equation a) to eliminate the x component. ...
Step Three: substitute the value of y into either equation to find the value of x.
In order to solve this, start by adding 1 to both sides of the equation.
m-1=2
+1 +1
-----------
m=3
The solution to your equation is 3.
You can also check to see if this is true by replacing m with 3.
m-1=2
3-1=2
250 * 0.20 = $50 sale

A = 1/2h(b1 + b2)
2A = h(b1 + b2)
2A/h = b1 + b2
b1 = 2A/h - b2
