How do you find the value of #x# given #5x-3=12?#

Answer 1

Savannah Anderson

See the entire solution process below:

Step 1) Add #color(red)(3)# to each side of the equation to isolate the #x# term while keeping the equation balanced:

#5x - 3 + color(red)(3) = 12 + color(red)(3)#

#5x - 0 = 15#

#5x = 15#

Step 2) Divide each side of the equation by #color(red)(5)# to solve for #x# while keeping the equation balanced:

#(5x)/color(red)(5) = 15/color(red)(5)#

#(color(red)(cancel(color(black)(5)))x)/cancel(color(red)(5)) = 3#

#x = 3#

To find the value of ( x ) in the equation ( 5x - 3 = 12 ), you would first add 3 to both sides of the equation to isolate the term with ( x ). This gives you ( 5x = 15 ). Then, you divide both sides by 5 to solve for ( x ). So, ( x = 3 ).

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.
