Asap please i need answer

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

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
