R/10+4=5 two step equations with integers

So we have this equation:

r/10 + 4 = 5

FIrst, we can substract 4 in both sides

r/10 + 4 - 4 = 5 - 4

r/10  = 1

Now, we can multiply both sides per 10:

r/10 * 10 = 1 * 10

r = 10

And we know that r = 10, and that's the result of the equation.

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
