Question

18х=216, 7 (х+5)=196 помогите пожалуйста

Answer 1

18x=216
x=216/18
x=12

7x+35=196
7x=196-35
7x=161
x=161/7
x=23

Answer 2

18x= 216
X = 216/18=12
7(x+5)= 196
X+5= 196/7 =28
X = 28-5 = 23

Answer 3

To solve the equation 18x = 216, we need to isolate the variable x. We can do this by dividing both sides of the equation by 18.

Solving the equation 18x = 216:

Divide both sides of the equation by 18:

18x/18 = 216/18

Simplifying the equation:

x = 12

So, the value of x that satisfies the equation 18x = 216 is x = 12.

Now, let's solve the equation 7 + (x + 5) = 196.

Solving the equation 7 + (x + 5) = 196:

First, simplify the equation by combining like terms:

7 + x + 5 = 196

Combine the constants:

12 + x = 196

Next, isolate the variable x by subtracting 12 from both sides of the equation:

12 + x - 12 = 196 - 12

Simplifying the equation:

x = 184

So, the value of x that satisfies the equation 7 + (x + 5) = 196 is x = 184.

I hope this helps! Let me know if you have any further questions.
