Solve the system of equations -4x+8y=40−4x+8y=40 and -2x+y=-10−2x+y=−10 by combining the equations.

Idon’t understand this.. will someone ? will mark brainliest along with 20 points.

Graph the equationy= x+3[tex]y = x + 3[/tex]

Worth 100 points need the answers asap first row -x^2 2x^2 (x/2)^2 x^2 x is less than 2 x is greater than 2 x is less than or equal to 2 x is greater than or equal to 2 second row -5 -5/2 4 5 •2 is less than x& x is less than 4 •2 is less than or equal to x & x is less than or equal to 4 •2 is less than or equal to x& x is less than 4 •2 is less than x& x is less than or equal to 4
