Tell whether the given value is a solution of the equation.

a. y+6=17; y=11
y=11 is not or is a solution.



b. 7z=42; z=8
z=8 is not or is a solution

Respuesta :

Answer: a. y=11 is a solution

b. z=8 is not a solution

Step-by-step explanation:

a. if y+6=17, then y=17-6. 17-6=11, so y=11, making it a solution.

b. if 7z=42, then y=42/7. 42/7 is 6, not 8, so z=8 is not a solution.
