Y=2x+6 and y=-3x+16 for solving the system

Substitution

Step 1: Solve for x or y in either of the two equations. In the equations that you are given, y is already solved for you.

Step 2: Plug in 2x + 6 into the opposite equation.

   2x + 6 = -3x + 16
         - 6              - 6

   2x = -3x + 10
+ 3x  + 3x

   5x  =  10
    
    5        5

x = 2

Step 3: Plug in the x value into either equation.

y = 2(2) + 6
y = 4 + 6
y = 10

The final answer gets expressed as a coordinate pair: (x,y) (2,10)

I hope this helps you :)

28.3mm

Step-by-step explanation:

upper bound of front and back cover=0.75mm and lower bound=0.65mm

lower bound of page=0.135mm and upper bound=0.145mm

As there is a front and back cover we multiply the lower bound by 2

as there is 200 pages we multiply the lower bound by 200

(0.65*2)+(0.135*200)=28.3mm
