Answer:
Step-by-step explanation:
Its B I just took the test
The sequence you add 6 each time so I say 6
14 times
To evaluate this, you would divide 84 by 6, which is equal to 14.
Py +7 = 6y + qp
Solve the equation for y
To solve the equation for y we need to get y alone
Py +7 = 6y + qp
Subtract 6y from both sides
Py - 6y +7 = + qp
Subtract 7 from both sides
Py - 6y = + qp - 7
Now factor out y
(P - 6)y = qp - 7
Divide by P - 6 from both sides

X= fancy, y= plain
x+y= 7
28x+ 15y=131
solve by substitution
