If ED = x + 4 and DB = 3x - 8, find ED, DB, and EB

Tom [10]

Answer:

Part 1) $ED=10\ units$

Part 2) $DB=10\ units$

Part 3) $EB=20\ units$

Step-by-step explanation:

we know that

EB=ED+DB

ED=DB -----> given problem

Substitute the given values and solve for x

$x+4=3x-8$

$3x-x=4+8$

$2x=12$

$x=6$

<em>Find the value of ED</em>

$ED=x+4$

substitute the value of x

$ED=6+4=10\ units$

<em>Find the value of DB</em>

Remember that

ED=DB

therefore

$DB=10\ units$

<em>Find the value of EB</em>

EB=ED+DB

$EB=10+10=20\ units$
