How do you solve this linear equation # 3(2x + 1) = 2x - 9#?

Answer 1

Eli Assouline

#color(blue)(x=-3#

#3 * (2x+1) = 2x-9#

#3 * (2x) + 3 * (1) = 2x-9#

#6x + 3 = 2x-9#

#6x -2x= -9-3#

#4x= -12#

#x=-12/4#

#color(blue)(x=-3#

To solve the linear equation 3(2x + 1) = 2x - 9, follow these steps:

Distribute the 3 on the left side of the equation: 6x + 3 = 2x - 9
Move all terms involving x to one side of the equation and constants to the other side: 6x - 2x = -9 - 3
Combine like terms: 4x = -12
Divide both sides by 4: x = -3
