17. Solving a system of equations Transcript
Solve the following system of equations for z and for y:
System of Equations:
Value of z
Value of y
y=9+3z
y=39−3z
Solve the following system of equations for a and for b:
System of Equations:
Value of a
Value of b
4a+2b=20
15a+5b=60
Plot the following system of equations on the following graph.
System of Equations:
p=6−2q
p=4+q
Note: Use the orange line (square symbols) to plot the first equation, and use the blue line (circle symbols) to plot the second equation.
p = 6 - 2q
p = 4 + q
