N/45 + n/35 = 2.5
[7n + 9n]/35 = 787.5
16n = 787.5
n = 787.5/16
n = 49.21875 miles
Answer: 49.21875
First no. = x
Second no. = y
Equation Formation.
x = 2 y + 5
x - 2 y = 5.........equation (i)
x + y - 1 = 16
x + y = 17............. equation(ii)
Solving Equation
x + y = 17
x - 2 y = 5
⇅
3 y = 12
y = 4
x = 2 y +5
x = 2(4) + 5
x = 13
Answer = 4 , 13
Answer:
y= 2x-2
Step-by-step explanation:
Use the linear equation.
y= mx+b
indentify what you already know
x= 2 and y= 2 and m(slope)= 2
we are solving for b, so lets plug in what we have.
2= 2(2)+b
Simplify.
2= 4+b
Subtract 4 from both sides.
-2= b
Rewrite your equation wihtout the x and y values.
y= 2x-2
