Answer:

x=±3 sqrt(2)

Step-by-step explanation:

3x^2 - 6 = 48

Add 6 to each side

3x^2 - 6+6 = 48+6

3x^2 = 54

Divide each side by 3

3x^2/3 =54/3

x^2 = 18

Take the square root of each side

sqrt(x^2) =sqrt(18)

x =sqrt(18)

We know sqrt(ab) = sqrt(a) sqrt(b)

x =sqrt(9)sqrt(2)

x=±3 sqrt(2)

Solve the equation for x. 2x + 22 = 4(x+3)
shusha [124]

Answer:

x = 5

Step-by-step explanation:

We have the algebraic expression and are asked to solve for x.

To solve, we need to isolate x.

2x + 22 = 4(x + 3)

Distribute :

2x + 22 = (4(x) + 4(3))

2x + 22 = 4x + 12

Subtract 12 from both sides :

2x + 10 = 4x

4x = 2x + 10

Subtract 2x from both sides :

2x = 10

Divide 2 from both sides to get x alone :

x = 5
