Answer:
C.E.: x <em>=/=</em> -4
Step-by-step explanation:
Multiply the first digit by 3 then subtract the answer by 2. Rule: x 3 - 2
Remember you can do anything to an equation as long as you do it to both sides
2x+3(x-4)=x-20
first distribute
2x+3(x)+3(-4)=x-20
2x+3x-12=x-20
5x-12=x-20
minus x both sides
4x-12=-20
add 12 to both sides
4x=-8
divide both sides by 4
x=-2
