What is the solution of the equation 10z − 6 = 24 solving for z ?(1 point)
To solve the equation 10z - 6 = 24 for z, we need to isolate the variable z.
The first step is to add 6 to both sides of the equation:
10z - 6 + 6 = 24 + 6
10z = 30
Then, divide both sides of the equation by 10 to solve for z:
(10z)/10 = 30/10
z = 3
Therefore, the solution to the equation is z = 3.
The first step is to add 6 to both sides of the equation:
10z - 6 + 6 = 24 + 6
10z = 30
Then, divide both sides of the equation by 10 to solve for z:
(10z)/10 = 30/10
z = 3
Therefore, the solution to the equation is z = 3.
Jonny is solving this equation for n : 8 + 3n = 20 . His first step is to subtract 8 from both sides of the equation. Why?(1 point) Responses He needs to follow the order of operations. He needs to follow the order of operations. 8 is the first term in the equation. 8 is the first term in the equation. He needs to reverse the order of operations. He needs to reverse the order of operations. 8 is attached to 3n by subtraction. 8 is attached to 3 n by subtraction.
Jonny subtracts 8 from both sides of the equation to isolate the variable n. By subtracting 8 from both sides, he is eliminating the constant term on the left side of the equation so it does not affect the variable term. This allows him to directly solve for n.
