Answer:
z= 1
Explanation:
Rewrite the equation as
15(z−1/5)z12
Apply the distributive property
15z+15(−1/5)= 12
Cancel the common factor of 5
15z+3*−1= 12
Multiply 3 by −1
15z−3= 12
Divide each term by 15 and simplify
5z−1 = 4
Since the expression on each side of the equation has the same denominator, the numerators must be equal
5z−1= 4
Move all terms not containing z to the right side of the equation
5z= 5
Divide each term by 5 and simplify
z = 1
