Write Equation Simplify: Write down the first equation from the system.The first equation is 14=z−(−12).We need to simplify the right side of the equation by removing the parentheses.
Solve for z: Simplify the right side of the equation.Since subtracting a negative is the same as adding a positive, we have z−(−12)=z+12.Now the equation is 14=z+12.
Write Second Equation: Solve for z by isolating it on one side of the equation.To do this, we subtract 12 from both sides of the equation.14−12=z+12−12This simplifies to 2=z.
Combine Results: Write down the second equation from the system.The second equation is simply z=.This indicates that z is equal to whatever value we find from the first equation.
Combine Results: Write down the second equation from the system.The second equation is simply z=.This indicates that z is equal to whatever value we find from the first equation.Combine the results from both equations.Since the first equation simplifies to 2=z and the second equation is z=, we can conclude that z=2.
