In the figure below, tan b = 3/4. If BC = 15 and DA = -4, What is the length of DE I will give brainliest for the first person the answer with the right answer

all it means is function 3

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
