Solve this pair of linear equations 10p+15q=65 and 10p-8q=-4 by using elimination method..Whole solutionStep by step

Answer»

Answer:

q=3

p=2

Step-by-step explanation:

10p+15q=65

10p-8q= -4

to ELIMINATE p;

subtract EQUATION (2) from (1)

23q=69

q=3

substitute q=3 in equation(2)

10p-8(3)= -4

10p-24= -4

10p=20

p=2
