Iven: x + 2y = -6. Solve for y.

y = -x/2 -3

Step-by-step explanation:

So there are LOTS of ways you can choose to do this, but this is how i do it:

I like to move all the x to one side first, so:

2y = -x -6

Then we have to divide everything by 2 to get y on its own:

y = -x/2 -3

*you can divide first too if you want, i find that this keeps it nice and simple though

Hope this helped : )

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
