Question

Solve the equation : (3.2y-1.8)-(5.2y+3.4)=-5.8

Answer 1

y= -11/2

Explanation

3.2y-+1.8-5.2y-3.4=-5.8

Collect like terms

-2y-5.2=-5.8

Move the constant to the right

-2y=5.8+5.2

Calculate

-2y=11

Divide

y=-11/2

Answer 2

y = 0.3

Explanation:

`(3.2y-1.8)-(5.2y+3.4)=-5.8 \\ \\ = 3.2y - 1.8 - 5.2y - 3.4 = - 5.8 \\ \\ 3.2y - 5.2y - 1.8 - 3.4 = - 5.8 \\ \\ - 2y - 5.2 = - 5.8 \\ \\ - 2y = 5.2 - 5.8 \\ \\ - 2y = - 0.6 \\ \\ y = ( - 0.6)/( - 2) \\ \\ y = 0.3`
