<span>See examples for the method to solving literal equations for a given variable: Solve A = bh for b. Since h is multiplied times b, you must divide both sides by h in order to isolate b. Since (c+d) is divided by 2, you must first multiply both sides of the equation by 2</span>
BC would equal the same as EF, they are similar. All you would have to do is figure out the pre image (BC) of EF.
Answer:
19
Step-by-step explanation:
f(x)=2/3
2/3=-1/3x+7
Subtract 7 from both sides
2/3-7=-1/3x
-6 1/3 = -1/3x
Multiply both sides by -3
-3(-6 1/3)=-1/3x(-3)
19 = x
ATQ


Now




From all equations




Now
Adding 3 and 4


One side won't be covered hence
There’s no solution because x is less than 3 there is no way is greater than 5.
Hope this helps!
