You asked:

Calculate the value of x+y4−92zx + \frac{y}{4} - \frac{9}{2 z} when x=2x = 2, y=4y = 4, and z=−3z = -3.

MathBot Answer:

x+y4−92z=92x + \frac{y}{4} - \frac{9}{2 z} = \frac{9}{2}

x+y4−92z=−92(−3)+44+2=−92(−3)+1+2=−−923+1+2=1+2+32=92\begin{aligned}x + \frac{y}{4} - \frac{9}{2 z}&=\frac{-9}{2 \left(-3\right)} + \frac{4}{4} + 2\\&=\frac{-9}{2 \left(-3\right)} + 1 + 2\\&=\frac{-- \frac{9}{2}}{3} + 1 + 2\\&=1 + 2 + \frac{3}{2}\\&=\frac{9}{2}\end{aligned}
