Please help solve!! i need my work need to me shown so please help me! ❤️

Step-by-step explanation:

multiply the first equation by 5 and the second by 2

5(3x+2y=-7)

2(2x-5y=8)

15x+10y=-35

4x-10y=16

add them

19x=-19

divide both sides by 19

x=-1

bring the value of x in either equation 1 or 2

in 1

3(-1)+2y=-7

-3+2y=-7

2y=-7+3

2y=-4

divide both sides by 2

y=-2

step-by-step explanation:

i hate black

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
