Answer 3

Let's solve the given equations step by step:

1. Equation 1: 3x - 16 + 25 = 5x - 16 + 3

First, combine like terms on both sides of the equation: 3x + 9 = 5x - 13

Next, move the variable terms (with x) to one side of the equation and the constant terms to the other side: 3x - 5x = -13 - 9 -2x = -22

Finally, solve for x by dividing both sides by -2: x = (-22) / (-2) x = 11

So the solution for the first equation is x = 11.

2. Equation 2: 2.5(3 - 2y) - 2.5(2y - 3) = 2.5y - 1

First, distribute the 2.5 on both terms inside the parentheses: 7.5 - 5y - 5y + 7.5 = 2.5y - 1

Combine like terms on both sides of the equation: 15 - 10y = 2.5y - 1

Next, move the variable terms (with y) to one side of the equation and the constant terms to the other side: -10y - 2.5y = -1 - 15 -12.5y = -16

Finally, solve for y by dividing both sides by -12.5: y = (-16) / (-12.5) y = 1.28

So the solution for the second equation is y = 1.28.
