Question

If 6(2x+1) is equal to -36-2x, what is the value of 3x

Answer 1

6(2x + 1) = -36 - 2x
12x + 6 = -36 - 2x
12x + 2x = -36-6
14x = -42
X = -3

Answer 2

Answer:

The value of 3x is -9

Step-by-step explanation:

Given Equation

$6(2x + 1) = - 36 - 2x$

Step 1

• Distribute 6 in the expression.

$12x + 6 = - 36 - 2x$

Step 2

• Combine like terms and solve the equation for x-term

$12x + 2x = - 36 - 6 \\ 14x= - 42 \\ x = \frac{ - 42}{14} \longrightarrow \frac{ - 3}{1} \\ x = - 3$

But we want to know what is the value of 3x.

Step 3

• Substitute the value of -3 in 3x.

$3x = 3( - 3) \\ 3x = - 9$

Hence, the value of 3x is -9
