Solve equation 3x-5y=7 5x-2y=-1 by elimination

x= -1, y= -2

Step-by-step explanation:

Multiply both sides of the equation by -2.

-6x + 10y= -14

5x - 2y= -1

Sum the equations vertically to eliminate at least one variable.

19x= -19

Divide both sides of the equation by 19.

x=-1

Substitute the given value of x into the equation 5x (-1) - 2y= -1.

Solve the equation for y.

y=-2

The possible solution of the system is the ordered pair (x,y)

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
