40 + 5x = y
X is how many weeks she saves
Y is the total savings after 12 weeks
Plug in 12 into the x
40+5(12) = y
40 + 60 = y
100 = y
She will have saved $100 after 12 weeks
An increase on down payment, will decrease a mortgage payment
Answer
D. Down payment
2x - 6y = 14
2x = 6y + 14
x = 3y + 7.....so sub in 3y + 7 for x in the other equation
4x - y = 9
4(3y + 7) - y = 9
12y + 28 - y = 9
12y - y = 9 - 28
11y = - 19
y = -19/11
x = 3y + 7
x = 3(-19/11) + 7
x = -57/11 + 7
x = -57/11 + 77/11
x = 20/11
solution is : (20/11, -19/11) <==
A puddle
