Part A
start by naming the variables you will be using in the system of equation
x= number of two-point baskets
y= number of three-point baskets
since she did 23 baskets the first equation representing the number of baskets she made will be
[tex]x+y=23[/tex]the second equation will be for the points, taking into account that x is 2 points and y is 3 points and she made 53 points.
[tex]2x+3y=53[/tex]Part B
Since the equations are not in the slope-intercept form they will be more complicated to graph, which using substitution it will be faster to find the solution of the system.
However both methods could be used.
Part C
[tex]\begin{gathered} x+y=23 \\ 2x+3y=53 \end{gathered}[/tex]
