How do you solve #4(2x - 1) - 3 = 9(x - 4)#?

Answer 1

Genesis Allen

#color(blue)(x=29#

#4(2x−1)−3=9(x−4)#

#4 * 2x + 4 * (−1) −3=9 * (x) + 9 * (−4)#

#8x -4 −3= 9x -36#

#8x -7= 9x -36#

# -7 +36= 9x - 8x#

#29 =x# #color(blue)(x=29#

First, distribute the 4 on the left side of the equation and the 9 on the right side. Then, combine like terms on each side. Next, isolate the variable term by moving all terms without the variable to one side of the equation and terms with the variable to the other side. Finally, solve for the variable by dividing both sides by the coefficient of the variable. The solution for x is 11/7.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
