Question

Solve for y c=7(y-k)

Answer 1

Concept

You are to make y the subject of the formula or subject of the relation.

Next, write the equation and solve for y.

c = 7(y - k)

first, multiply 7 with y and k to remove the bracket.

c = 7y - 7k

Next, move negative 7k to the left of the equation.

c + 7k = 7y

Divide through by 7 to make y subject of the relation.

`\begin{gathered} We\text{ have} \\ \frac{c\text{ + 7k}}{7}\text{ = y} \\ or \\ y\text{ = }(c)/(7)\text{ + }(7k)/(7) \\ y\text{ = }(c)/(7)\text{ + k} \end{gathered}`

Final answer

y = c/7 + k or y = (c + 7k) /7
