What is the value of y in the solution to this system of equations? 6y + x = – 59 x = – 2y + 9

Answer 1

y=-17/2 =-8.5 is the solution

to 2 equations

6y+x=-59

x=-2y +9

graph the 2 equations, find the intersection point (-8, -17/2) = (x,y)

check the answers

6(-17/2)+(-8) = -51-8 = -59

-8= -2(-17/2)+9=-17+9=-8 the answers work

or

do substitution elimination

or matrix algebra with row operations

Answer 2

6y+x=-59

6y+(-2y+9)=-59

6y-2y+9=-59

4y=-68

y=-17
