Answer 2

It looks like you have a set of equations, and you want to solve for the variables x and y in each equation. Let's go through each equation step by step:

1a) x - 2.5 = 6.5

To solve for x, you can isolate x by adding 2.5 to both sides of the equation:

x - 2.5 + 2.5 = 6.5 + 2.5 x = 9

So, the solution to the first equation is x = 9.

1b) 5.6 + y = -4.5

To solve for y, you can isolate y by subtracting 5.6 from both sides of the equation:

5.6 + y - 5.6 = -4.5 - 5.6 y = -10.1

So, the solution to the second equation is y = -10.1.

1c) 2.3 + x = -5.3

To solve for x, you can isolate x by subtracting 2.3 from both sides of the equation:

2.3 + x - 2.3 = -5.3 - 2.3 x = -7.6

So, the solution to the third equation is x = -7.6.

1d) y - 4.9 = 2.9

To solve for y, you can isolate y by adding 4.9 to both sides of the equation:

y - 4.9 + 4.9 = 2.9 + 4.9 y = 7.8

So, the solution to the fourth equation is y = 7.8.

2a) -2x = 0.8

To solve for x, you can isolate x by dividing both sides of the equation by -2:

(-2x) / (-2) = 0.8 / (-2) x = -0.4

So, the solution to the fifth equation is x = -0.4.

2b) 2.5y = -10

To solve for y, you can isolate y by dividing both sides of the equation by 2.5:

(2.5y) / (2.5) = -10 / 2.5 y = -4

So, the solution to the sixth equation is y = -4.

2c) 3x = 2

To solve for x, you can isolate x by dividing both sides of the equation by 3:

(3x) / 3 = 2 / 3 x = 2/3

So, the solution to the seventh equation is x = 2/3.

2d) -1.2y = 0.63

To solve for y, you can isolate y by dividing both sides of the equation by -1.2:

(-1.2y) / (-1.2) = 0.63 / (-1.2) y = -0.525

So, the solution to the eighth equation is y = -0.525.

It seems you have completed all the equations. If you have any further questions or need additional assistance, please feel free to ask.
