Question

Check whether you = 1 is a solution of the equation-
1.2 (3y - 4) - 0.3 (2y - 6) = 0 or not.

Answer 1

Answer:

2(3*1-4)-0.3(2*1-6)=0

2(3-4)-0.3(2-6)

2(-1)-0.3(-4)

-2-1.2

=-3.2

So, it is not equal to 0

Answer 2

1.2 (3y - 4) - 0.3 (2y - 6) = 0

Step-by-step explanation:

Firstly, lets solve the question:

$1.2 (3y - 4) - 0.3 (2y - 6) = 0\\3.6y - 4.8 - 0.6y - 1.8=0\\3y-6.6=0\\3y=0+6.6\\3y=6.6\\y=\frac{6.6}{3} \\y=2.2$

CHECK:

2(3*1-4)-0.3(2*1-6)=0

2(3-4)-0.3(2-6)

2(-1)-0.3(-4)

-2-1.2

=-3.2

that's -3.2≠0

so, y=1 is not a solution of 1.2 (3y - 4) - 0.3 (2y - 6) = 0
