Brock is training for a crossfit competition. he began the training by completing pull-ups and box jumps. originally, his training plan had him completing pull-ups and box jumps at a ratio of 5: 4. after two months of training, he decided to focus on his leg strength and adjusted his ratio to 2: 7. if he completed 53 box jumps at the end of his training, how many pull-ups did he complete in the initial stage of training?

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
