x = 9
Step-by-step explanation:
10x - 30 = 15 + 5x
First, subtract 5x from both sides to get all x terms on the left side.
5x - 30 = 15
Now add 30 to both sides.
5x = 45
Divide both sides by 5.
x = 9
Ответ:
x =9
Step-by-step explanation:
10x-30=15+5x
Subtract 5x from each side
10x-5x -30 = 15+5x-5x
5x-30 = 15
Add 30 to each side
5x-30+30 = 15+30
5x =45
5x/5 = 45/5
x =9
