Linear Equations

100

2x - y = 6

x - y = 2

x = 4

y = 2

200

2x + y = 35

3x + 4y = 65

x = 15

y = 5

300

Find the error and describe which property was incorrectly applied.

Then, find the correct answer:

3(x-2) = 2(x+4)

3x-2 = 2x+4

x = 6

Distributive Property 

Correct answer: x=14

400

(2x+1)/4 = (3x-1)/7

x = -11/2

500

(3x+4)/2 = (5x+10)/5

x = 0
