Generate a table of values from the equations below: a) y - x = -3 b) x + y = 5

Ongeza $x$ pande zote mbili za kanuni:

$$y - x + x = -3 + x$$ $$y = x - 3$$

• Wakati $x = 1$: $y = 1 - 3 = -2$
• Wakati $x = 2$: $y = 2 - 3 = -1$
• Wakati $x = 3$: $y = 3 - 3 = 0$
• Wakati $x = 4$: $y = 4 - 3 = 1$

Jedwali (a) lililokamilika:

$$\begin{array}{|c|c|} \hline x & y \\ \hline 1 & -2 \\ \hline 2 & -1 \\ \hline 3 & 0 \\ \hline 4 & 1 \\ \hline \end{array}$$

Toa $x$ pande zote mbili za kanuni:

$$x + y - x = 5 - x$$ $$y = 5 - x$$

• Wakati $x = 1$: $y = 5 - 1 = 4$
• Wakati $x = 2$: $y = 5 - 2 = 3$
• Wakati $x = 3$: $y = 5 - 3 = 2$
• Wakati $x = 4$: $y = 5 - 4 = 1$
