Use algebra to find the point of intersection of the two lines whose equations are provided. Use Example 7 as a guide. 3x + y = 9 and 4x − y = 5

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

the answer is d

for problems like this theres an app, its photomath that explains the problem and gives the answer hope i

i would love   to but there is no graph shown
