How do you solve #(6x + 4) + ( 12x + 26) = 180#?

Answer 1

Eva Abramson

#x = 8 2/3#

Solve for #x#.

#6x + 4 + 12x + 26 = 180#

#18x + 30 = 180#

#18x + 30 - 30 = 180 - 30#

#18x = 150#

#(18x)/18 = 150/18#

#x = 8.3333... = 8 2/3#

To solve the equation (6x + 4) + (12x + 26) = 180, first combine like terms:

6x + 4 + 12x + 26 = 180 (6x + 12x) + (4 + 26) = 180 18x + 30 = 180

Next, isolate the variable by subtracting 30 from both sides:

18x + 30 - 30 = 180 - 30 18x = 150

Now, divide both sides by 18 to solve for x:

18x / 18 = 150 / 18 x = 150 / 18 x = 25/3 or approximately 8.33

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.
