Answer 1

Answer:

$\boxed {\boxed {\sf y= -1.2 }}$

Step-by-step explanation:

We are asked to solve the following equation for y.

$-2y-4.2= 1.8 + 3y$

To solve for y, we have to isolate the variable by performing the inverse operations.  First, move all the terms without a variable or the constants to one side, and the terms with a variable to the other side.

4.2 is being subtracted and the inverse operation of subtraction is addition. Add 4.2 to both sides.

$-2y-4.2 +4.2= 1.8 + 3y+ 4.2$

$-2y=1.8 + 4.2 + 3y$

$-2y= 6 + 3y$

3y is being added and the inverse operation of addition is subtraction. Subtract 3y from both sides.

$-2y-3y= 6+ 3y -3y$

$-2y-3y= 6$

$-5y=6$

y is being multiplied by -5. The inverse operation of multiplication is division. Divide both sides by -5.

$\frac {-5y}{-5}= \frac{6}{-5}$

$y=- 1.2$

Check the answer by substituting -1.2 back into the original equation.

$-2 (-1.2)-4.2 = 1.8 + 3(-1.2)$

$2.4-4.2=1.8 + - 3.6$

$-1.8 = -1.8$

This checks out, so we know our answer is correct.
