Beat the Test #1 on page 105: Lyle and Shaun open savings accounts at the same time. Lyle deposits $100 initially and adds $20 per week. Shaun
deposits $500 initially and adds $10 per week. Lyle wants to know when he will have the same amount in his savings
account as Shaun has.
Part A: Write two equations to represent the amounts of money Lyle and Shaun have in their accounts.
Part B: Which method would you use to solve the problem, substitution or graphing? Explain your answer.
Part C: After how many weeks of making the additional deposits will Lyle have the same amount of money as Shaun?

it's both, now can you answer my most recent question?

step-by-step explanation:

570, the answer is 570, hope it

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.
