How do you solve #4(x − 1) − (x + 6) =2#?

Answer 1

Eli Assouline

see a solution process below;

#4(x - 1) - (x + 6) = 2#

taking out the brackets;

#4x - 4- x - 6 = 2#

assemble similar terms;

#4x - x - 4 - 6 = 2#

streamlining

#3x - 10 = 2#

add #10# to both sides;

#3x - 10 + 10 = 2 + 10#

#3x = 12#

dividing by the coefficient of #x#

#x = 12/3#

#x = 4#

To solve the equation 4(x − 1) − (x + 6) = 2:

Distribute the terms inside the parentheses: 4x - 4 - x - 6 = 2
Combine like terms: 3x - 10 = 2
Add 10 to both sides: 3x = 12
Divide both sides by 3: x = 4

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.
