Consider this system of linear equations: 22x − y = -23 (equation 1) 11x + 12y = 1 (equation 2) to find the value of x, you need to substitute in equation 2. the value of x is .

Answer

x = -1.

Step-by-step explanation:

From equation 1:

y = 22x + 23

Plug this into equation 2:

11x + 12(22x + 23) = 1

11x + 264x + 276 = 1

275x = -275

x = -1

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
