Question

Solve the system of equations y=2x+7 y=5x-7 x= Y=

Answer 1

Answer:

x = 14/3

y = 16.3333333333

Step-by-step explanation:

Step 1. equal them to each other and solve for x

2x + 7 = 5x - 7

5x - 2x = -14

3x = 14

x = 14/3

Step 2. Plug in the value of x and solve for y

y = 5x - 7

y = 16.3333333333

tadah!

Answer 2

Answer:

x= 14/3

y= 49/3

Step-by-step explanation:

y= 2x+7

y= 5x-7

-2x + y = +7

(-5x + y = -7) * (-1)

-2x + y = +7

+5x - y = +7

3x +0y= 14

3x= 14

x= 14/3

replace x in any equation from these 2:

y= 2x+7

y= 5x-7

ill chose this :

y= 2x+7

y= 2(14/3) +7

y= 49/3
