Answer:
solution :
x = 4
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
5*(x-10)-(30-15*x)=0
Step by step solution :
Step 1 :
Equation at the end of step 1 :
5 • (x - 10) - (30 - 15x) = 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
20x - 80 = 20 • (x - 4)
Equation at the end of step 3 :
20 • (x - 4) = 0
Step 4 :
Equations which are never true :
4.1 Solve : 20 = 0
Step-by-step explanation:
The correct answer is 12

Answer:
3+sqrt(13/2)
3-sqrt(13/2)
Step-by-step explanation:
2 (x-3) ^2 =13
Divide each side by 2
2/2 (x-3) ^2 =13/2
(x-3) ^2 =13/2
Take the square root of each side
sqrt((x-3) ^2) =±sqrt(13/2)
x-3 = ±sqrt(13/2)
Add 3 to each side
x-3+3 = 3±sqrt(13/2)
x = 3±sqrt(13/2)
