−5z−15=−10z+5
To solve the equation, start by combining like terms on both sides of the equation:
-5z - 15 = -10z + 5
Next, move all terms involving z to one side of the equation by adding 10z to both sides:
-5z + 10z - 15 = 5
Combine like terms again:
5z - 15 = 5
Next, simplify the equation further by adding 15 to both sides:
5z - 15 + 15 = 5 + 15
The -15 and +15 on the left side cancel each other out:
5z = 20
Finally, divide both sides of the equation by 5 to solve for z:
(5z)/5 = 20/5
The 5 on the left side cancels out, leaving:
z = 4
Therefore, the solution to the equation is z = 4.
2(9z+2)−5=197
To solve the equation, start by simplifying the expression inside the parentheses:
2(9z + 2) - 5 = 197
First, distribute the 2 to both terms inside the parentheses:
18z + 4 - 5 = 197
Combine like terms:
18z - 1 = 197
Next, add 1 to both sides of the equation to isolate the variable term:
18z - 1 + 1 = 197 + 1
The -1 and +1 on the left side cancel each other out:
18z = 198
Finally, divide both sides of the equation by 18 to solve for z:
(18z)/18 = 198/18
The 18 on the left side cancels out, leaving:
z = 11
Therefore, the solution to the equation is z = 11.
3(x−6)=6
To solve the equation, start by distributing the 3 to the terms inside parentheses:
3(x - 6) = 6
This becomes:
3x - 18 = 6
Next, move the constant term to the other side of the equation by adding 18 to both sides:
3x - 18 + 18 = 6 + 18
The -18 and +18 on the left side cancel each other out:
3x = 24
Finally, divide both sides of the equation by 3 to solve for x:
(3x)/3 = 24/3
The 3 on the left side cancels out, leaving:
x = 8
Therefore, the solution to the equation is x = 8.
