Can you do this 3(2x - 4) = 8

x =10/3

Step-by-step explanation:

3(2x - 4) = 8

Distribute

6x - 12 = 8

Add 12 to each side

6x-12+12 = 8+12

6x = 20

Divide each side by 6

6x/6 = 20/6

x =10/3

y=mx+b is the final answer!   : )

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
