What is the answer for this eqation? 20-3x=9-7x

x = - 11/4

Step-by-step explanation:

20- 3x = 9 - 7x

Add 7x to both sides

20 - 3x + 7x  =  9 - 7x + 7x

20 + 4x = 9    

Now,Subtract 20 from both sides

20 -20 + 4x = 9 - 20

             4x = -11        {Divide both sides b 4}

               x = -11/4

= -11/4

Step-by-step explanation:

Rearrange terms

−3+20=9−7

− 3 + 20 = − 7 + 9

Subtract  20  from both sides of the equation

− 3 + 20 = − 7 + 9

− 3 + 20 − 20 = − 7 + 9 − 20

Simplify / Subtract the numbers

− 3 = − 7 − 1 1

Add  7 7x 7x  to both sides of the equation

− 3 = − 7 − 1 1

− 3 + 7 = − 7 − 1 1 + 7

Simplify / Combine like terms

4 = − 1 1

Divide both sides of the equation by the same term

4 = −11

4/4 = -11/4

Simplify / Cancel terms that are in both the numerator and denominator

= -11/4

the answer

b. they are parallel and will never intersect.
