How do you solve #\frac{1}{5} x + 4= 12#?

Answer 1

Isaiah Anthony

#x=40#

#1/5x+4=12#

1)subtract 4 from both sides: #=> 1/5x+4-4=12-4#

#=> 1/5x=8#

2) multiply both sides with 5 : #=> 1/cancel5x*cancel5=8*5#

#=> x=40#

To solve the equation (\frac{1}{5}x + 4 = 12), follow these steps:

Subtract 4 from both sides of the equation: [\frac{1}{5}x + 4 - 4 = 12 - 4] [\frac{1}{5}x = 8]
To isolate (x), multiply both sides of the equation by 5 (the reciprocal of (\frac{1}{5})): [\frac{1}{5}x \times 5 = 8 \times 5] [x = 40]

So, the solution to the equation (\frac{1}{5}x + 4 = 12) is (x = 40).

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.
