Question

What’s x-2 = 3x-84

Answer 1

Answer:

$\huge \boxed{x=41}$

Step-by-step explanation:

First thing you do is add by 2 from both sides of equation.

$\displaystyle x-2+2=3x-84+2$

Simplify.

$\displaystyle x=3x-82$

Then you subtract by 3x from both sides of equation.

$\displaystyle x-3x=3x-82-3x$

Simplify.

$\displaystyle -2x=-82$

Divide by -2 from both sides of equation.

$\displaystyle \frac{-2x}{-2}=\frac{-82}{-2}$

Simplify, to find the answer.

$\displaystyle -82\div-2=41$

$\large \boxed{x=41}$, which is our answer.

Answer 2

Answer:

x = 41

Step-by-step explanation:

Subtract the lower term in both sides

3x - x = 2x

2x - 84 = -2

Add 84 in both sides

84 -2 = 82

2x = 82

Divide 2 in both sides

2x/2 = x

82/2 = 41

Simplify

x = 41

Answer

x = 41
