yz means to multiply y times z. So you just replace the values, and do the multiplication.
x=2*5 x=10
y=5-x
x = yz/(y - z)

solve x=yz for the variable y
yz means to multiply y times z. So you just replace the values, and do the multiplication.
x=2*5 x=10
y=x+4
y=5-x
x = yz/(y - z)
x=4 y=x+3 y=4+3 y=7
16
y=7+x =x=7-x
1/x = 1/y + 1/zx = ( yz ) / (y + z)

Are you sure the directions don't have "solve the equation as x=___ and y=___"
