How do you solve #3=x+3-5x#?

Answer 1

Nathan Axel

#x=0#

# "collect like terms on the right side of the equation" #

#3=-4x+3#

# "subtract 3 from both sides" #

#4xcancel(+3)cancel(-3)# for #3–3

#0=-4xrArrx=0#

Blue #color "As a check"#

# "substitute x = 0 into the right side" #

"left side"#0+3-0=3

"#x=0" is the answer.

To solve the equation 3 = x + 3 - 5x, you would first combine like terms by adding or subtracting the coefficients of the variable x. Then, you would isolate the variable x on one side of the equation by performing inverse operations (addition, subtraction, multiplication, or division) to both sides of the equation until x is alone. Finally, you would solve for the value of x. Let's go through the steps:

3 = x + 3 - 5x

Combine like terms: 3 = 3 - 4x

Subtract 3 from both sides to isolate the variable term: 0 = -4x

Divide both sides by -4 to solve for x: 0 / -4 = x

x = 0

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.
