Under the action of sunlight plants convert carbon dioxide and water into glucose anf oxygen.
3X - 4Y = 9
-3X + 2Y = 9
first step is try to get rid of one of the variables and solve for the other one. In this example you dont need to manipulate the equations to get one variable to cancel.
the x term cancels out. add both equations
-2y = 18
y= - 9
now we plug the y term back into an original equation and solve for x
3x - 4(-9)=9
3x=-27
x=-9
hope that helps

Answer:
$92.43
Step-by-step explanation:
Original value of money paid is $79
Tip is 17% of $79 = $13.43
Total is the original value + the tip
79 x 0.17(this is because 17% is the same as 17/100 If you turn this to a decimal you get 0.17) = $13.43
Total = $13.43 + $79
$92.43 the 43 cents are whole so there is no need to round off.
