How do you solve #x + 3=7x + 15#?

Answer 1

Hazel Anglin

# color(blue)(x=-2#

#x+3=7x+15#

#x-7x= 15-3#

#-6x=12#

# color(blue)(x=-2#

To solve the equation (x + 3 = 7x + 15), you can follow these steps:

Subtract (x) from both sides to isolate the variable terms: (3 = 6x + 15).
Subtract 15 from both sides: (-12 = 6x).
Divide both sides by 6 to solve for (x): (x = -2).

So, the solution to the equation is (x = -2).

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.
