Answer 2

Let's solve each equation step by step:

1. 168 - y = 304

To isolate the variable "y," we need to move 168 to the other side of the equation by subtracting it from both sides:

168 - y - 168 = 304 - 168

Simplifying:

-y = 304 - 168

-y = 136

To solve for "y," we multiply both sides of the equation by -1 to get rid of the negative sign:

(-1)(-y) = (-1)(136)

y = -136

Therefore, the solution to the equation is y = -136.

2. m - 584 = 425

To isolate the variable "m," we need to move -584 to the other side of the equation by adding it to both sides:

m - 584 + 584 = 425 + 584

Simplifying:

m = 1009

Therefore, the solution to the equation is m = 1009.

3. 3128 - a = 1509

To isolate the variable "a," we need to move 3128 to the other side of the equation by subtracting it from both sides:

3128 - a - 3128 = 1509 - 3128

Simplifying:

-a = -1619

To solve for "a," we multiply both sides of the equation by -1 to get rid of the negative sign:

(-1)(-a) = (-1)(-1619)

a = 1619

Therefore, the solution to the equation is a = 1619.
