How do you solve #\frac { x } { 10} + 4= 3#?

Answer 1

Ethan Adkins

#x = -10#

Subtract #4# from both sides

# x/10 +4 - 4 = 3-4#

and then you are left with

#x/10 = -1#

Multiply both sides to cancel the #10# in the denominator

#10 * x/10 = -1 * 10 #

and then you are left with

#x = -1 * 10#

Simplify it and you are left with

#x = -10#

To solve the equation (\frac{x}{10} + 4 = 3), you can follow these steps:

Subtract 4 from both sides of the equation: (\frac{x}{10} + 4 - 4 = 3 - 4)
Simplify: (\frac{x}{10} = -1)
Multiply both sides by 10 to isolate (x): (10 \times \frac{x}{10} = -1 \times 10)
Simplify: (x = -10)

So, the solution to the equation is (x = -10).

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.
