Step-by-step explanation:
2) 8=n+3/-2
we cross multiply
n+3=8*(-2)
n+3= -16
n= -16 - 3
n= -19
lets check if we are correct
8=-19+3/-2
8= -16/-2
-16/-2=8
4) 9=x/2+6
we first calculate the fraction
x/2+6
L. c. m is 2
x/2+6/1=4x + 8/2=12x/2
2 times 2=4 plus x = 4x
2 times 1 =2 plus 6= 8
thats how i got 4x + 8/2
back to the question
9=12x/2
cross multiply
12x=9*2
12x=18
x=18/12
we will use 2 to divide it
9/2
3 will divide
3/2
x=3/2
Yes!
- you applied the distributive property
- combined like terms
- and answered the rest right!
