Write an equation for each of the following problems and then solve. a number and 15 total 45

x+15=45

  -15 15

    x=30

30+15=45

Equation: x + 15 = 45

Solved: n = 30

Step-by-step explanation:

You can think of this as saying, "A variable plus 15 equals 45"

Now that you have the equation, you can solve for the variable (in this case it's "n"), using the inverse operation.

Step 1: Isolate n by subtracting 15 from both sides of the equation

Recommended: To check your answer, substitute the result you got for "n" into the original equation:

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

correct answer is infinitely many solutions

step-by-step explanation:

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

solving the above equation:

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

combining like terms

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

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
