4(x+8)
because 4 is the greatest common factor of 4 and 32. you distribute the 4 into the parenthesis and get 4x+32
Answer:
x = 5 x = 1
Step-by-step explanation:
−3|x − 3| = −6
Divide each side by -3
−3/-3|x − 3| = −6/-3
|x − 3| = 2
An absolute value is equal to a positive and negative solution
x-3 =2 and x-3 = -2
Add 3 to each side
x-3+3 = 2+3 x-3+3 = -2+3
x = 5 x = 1
<u><em>subsitution</em></u> means subsituteing something for another and getting the answer
the way to do this is to get an easy equation and make it equal to only one placeholder so
y=2x
so you can subsitute y for 2x anywhere you see a y
3x+y=5
subsitutute
3x+2x=5
5x=5
divide both sides by 5
x=1
subsitute
y=2(1)
y=2
<u><em>elimination</em></u> is when you elimintate one of the terms by adding the equations together and canceling som of them out
so y=2x
subtract y from both sides
0=2x-y or 2x-y=0
add this to the second equation
3x+2x+y-y=0+5
5x=5
divide both sides by 5
x=1
subsitute
y=2(1)
y=2
x=1
y=2
(x,y) also known as (4,1)
