l=51
m=78
n=51
n and l have the same value since it’s an isosceles triangle, so that’s why I doubled 4x-9
What is the asnwer worked out to m-9=-13
1 answer:
Thus is a linear equation, so you want to isolate m so you can compare the variable m to a constant.
You begin by getting rid of -9 by adding 9 (its opposite) since a negative plus a positive can me zero. Then you add 9 to (-13) which is the same as 13-9 but with a negative value, so you get -4.
The answer is -4
