Hector solves this equation:
disa [49]

Answer:

9x+8=23      HOPE THIS HELPS

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

17+7x−9=19−2x+4

17+7x+−9=19+−2x+4

(7x)+(17+−9)=(−2x)+(19+4)(Combine Like Terms)

7x+8=−2x+23

7x+8=−2x+23

Step 2: Add 2x to both sides.

7x+8+2x=−2x+23+2x

9x+8=23

Step 3: Subtract 8 from both sides.

9x+8−8=23−8

9x=15

Step 4: Divide both sides by 9.

9x /9 = 15 /9

x= 5 /3

Eric traveled to two cities on a single highway. The total distance one way was 200 miles. The distance from his original locati
drek231 [11]
<span>Equation (1) x + y = 200

Eauation (2) x = y - 40

x represents the distance from the original location to the firstt city

y represents the distance from the first city to the second city.

Solution:

(1) x + y = 200

(2) x - y = - 40
----------------------

2x = 200 - 40

2x = 160

x = 160 / 2

x = 80

x + y = 200 => y = 200 - x = 200 - 80 = 120

Therefore the solution (x,y) is (80,120)

Answer: the pair of coordinates that represents the solution (in miles) to this system of equations is (80, 120) </span>
