    4(5n - 7) = 10n + 2
4(5n) - 4(7) = 10n + 2
     20n - 28 = 10n + 2
   - 10n         - 10n
     10n - 28 = 2
           + 28 + 28
            10n = 30
             10     10
                n = 3

Solve for x 5x + 3 - 2x = 24 (also don't have the answer be a fraction)
Yuki888 [10]

Answer:

x=7

Step-by-step explanation:

Let's solve your equation step-by-step.

5x+3−2x=24

Step 1: Simplify both sides of the equation.

5x+3−2x=24

5x+3+−2x=24

(5x+−2x)+(3)=24(Combine Like Terms)

3x+3=24

3x+3=24

Step 2: Subtract 3 from both sides.

3x+3−3=24−3

3x=21

Step 3: Divide both sides by 3.

For g(x)= (x+7)^2 + 6x determine the input of x when the output of g(x) =13
AURORKA [14]

Answer:

x = -2 or -18.

Step-by-step explanation:

(x+7)^2 + 6x = 13

x^2 + 14x + 49 + 6x - 13 = 0

x^2 + 20x + 36 = 0

(x + 2)(x + 18) = 0

x = -2, -18.
