A number is multiplied by 4 and then 12 is added. the result is 36. what is the number?

6

Step-by-step explanation:

4 * x + 12= 36

          -12  -12

4x = 24

x= 6

6

Step-by-step explanation:

The equation will look like this

n(4)+12=36

n=6

6(4)+12

24+12

36

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
