Question

Simplify 2(x+3y-3)-(2x+6y-7)

Answer 1

Step-by-step explanation: 2(X+3Y-3)-(2X+6Y-7) then we open the bracket

2X+3Y-6-2X-6Y+7 = 0 .......(1)

then we cancel 2X BECAUSE they have same value with opposite sign

3Y-6-6Y+7 = 0 .......(2)

-3Y+1= 0 .....(3)

3Y=1,

Y = 1/3 and X = 0

Answer 2

Answer: 1

Explanation:

2(x+3y-3)-(2x+6y-7)

2x + 6y - 6 - 2x - 6y + 7

-6 + 7
