Tao uses elimination to solve the following system of linear equations. -2x+4y=162x+2y=8which ordered pair is a solution to the system? a. (0, 4) b. (0, 8) c. (4, 0) d. (8, 0)

The correct answer is the first option.

If you want to use elimination, you can sum the two equations for example, so that the x's simplify:

Plug this value for y in one of the equations to derive the value of x:

So, the solution is

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
