X+2y=200 x-y= 50 What would be the first step to solve the given system for y

Multiply the second equation by -1, then add the equations together.

Step-by-step explanation:

x+2y=200  

x- y= 50

Multiply the second equation by -1 to eliminate the x

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.

step-by-step explanation:

table 3 represents a direct variation function. : )
