campbell_st · Answer

so to do this swap x and y.. so your equation is 

$$x = \frac{2y}{7} + 4$$

now make y the subject of the equation.

campbell_st · Answer

not quite... 

1st step
move the 4 by subtracting from both sides of the equation

then look at what you have

campbell_st · Answer

nope... start from the beginning 

$$x = \frac{2y}{7} + 4$$

subtract 4 from both sides of the equation
