Step-by-step explanation:

FULL QUESTION:

The highest scorer of the women's basketball championship was Jessica Bradley. She scored 149 more points than Tina Harner, her teammate. Together, Bradley and Harner scored 1563 points. How many points did each player score during the championship?

Let T = points scored by Tina Harner

J = points scored by Tina Harner

She scored 149 more points than Tina Harner, her teammate. This means;

J = T + 149...........(i)

Together, Bradley and Harner scored 1563 points. This means;

J + T = 1563 .........(ii)

How many points did each player score during the championship?

We have to find T and J.

Substitute value of J from eqn (i) into eqn (ii)

T + 149 + T = 1563

2T = 1563 - 149 = 1414

T = 1414 / 2 = 707

J = 707 + 149 = 856

Jessica Bradley - 856 Points

Tina Harner - 707 Points
