1.5−x=−4.5

3 answers

To solve for x in the equation 1.5 - x = -4.5, we need to isolate x on one side of the equation.

First, let's subtract 1.5 from both sides of the equation:

1.5 - x - 1.5 = -4.5 - 1.5

This simplifies to:

-x = -6

Next, let's multiply both sides of the equation by -1 to isolate x:

(-1)(-x) = (-1)(-6)

This simplifies to:

x = 6

Therefore, the solution to the equation 1.5 - x = -4.5 is x = 6.
6y - 9y + 6 = -12
To solve this equation, we will combine like terms and isolate the variable.

Starting with the given equation: 6y - 9y + 6 = -12

We can combine the y terms by subtracting 9y from 6y: -3y + 6 = -12

Next, we will isolate the variable y by subtracting 6 from both sides: -3y + 6 - 6 = -12 - 6

This simplifies to: -3y = -18

To solve for y, we need to divide both sides of the equation by -3: (-3y) / -3 = (-18) / -3

This further simplifies to: y = 6

Therefore, the solution to the equation 6y - 9y + 6 = -12 is y = 6.
