$\sf{\underline{\green{Given:-}}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• 1.2 (3y - 4) - 0.3 (2y - 6) = 0

$\sf{\underline{\green{Explanation:-}}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\longrightarrow \sf {1.2 (3y - 4) - 0.3 (2y - 6) = 0}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\longrightarrow \sf {3.6y - 4.8 - 0.6y + 1.8 = 0}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\longrightarrow \sf {3y - 3 = 0}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\longrightarrow \sf {3y = 3}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\longrightarrow \sf {y = \cancel\dfrac{3}{3}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\longrightarrow \sf {y = 1}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\:\:\:\:\dag\bf{\underline{\underline \red{Hence:-}}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• y = 1 is the solution of the given equation.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\rule{200}{2}$

Answer 2

Solution:

1.2 (3y - 4) - 0.3 (2y - 6) = or not.

⟶1.2(3y−4)−0.3(2y−6)=0

⟶3.6y−4.8−0.6y+1.8=0

⟶3y−3=0

⟶3y = 3

⟶y= 3/3

Y=1
