How do you solve #2a -( 5a-13) = 46#?

Answer 1

Eli Assouline

#color(blue)(a= -11#

#2a - (5a - 13) = 46#

#2a - 5a + 13 = 46#

#- 3a + 13 = 46#

#- 3a = 46 - 13#

#- 3a = 33#

#a = 33 /(-3)#

#a = -33/3#

#color(blue)(a= -11#

To solve the equation (2a - (5a - 13) = 46):

Distribute the negative sign inside the parentheses: (2a - 5a + 13 = 46).
Combine like terms: ((-3a + 13) = 46).
Subtract 13 from both sides: (-3a = 33).
Divide both sides by -3: (a = -11).

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.
