−7x−2y=14 6x+6y=18 Graph the system of equations.

1 answer:

3 0

X= -4
y= 7

you can multiply the top equation by 3, then both y's are cancelled or zeroed out. You add -21 and 6 to get -15x. Than you add 42 and 18 to get 60. So, -15x=60 and from there you do 60/-15 to get x=-4. Plug in what you got for x into any of the two equations to get y, which is 7.

4-d= -(d -4 ) -no solution infinitely many solutions -one solutions -two solutions

a_sh-v [17]

Answer: infinite solutions

Step-by-step explanation: any value of d makes the equation true. By simplifying the right side, we get -d + 4, which is the same as 4 - d, so we essentially get 4 - d = 4 - d.
