1y=2

y=2:1

y=2

Answer 3

To solve these equations, you'll want to isolate the variable (a in the first equation and y in the second equation) on one side of the equation. Here are the steps to solve each equation:

1. Solve for a in the first equation: 17 + 5a = 3a - 9

   First, subtract 3a from both sides of the equation to move the variable terms to one side: 17 + 5a - 3a = -9

   Simplify the left side of the equation: 2a + 17 = -9

   Next, subtract 17 from both sides to isolate 2a: 2a + 17 - 17 = -9 - 17

   Simplify: 2a = -26

   Finally, divide both sides by 2 to solve for a: (2a)/2 = (-26)/2

   a = -13

   So, the solution for the first equation is a = -13.

2. Solve for y in the second equation: 4 + 25y = 6 + 24y

   First, subtract 24y from both sides to move the variable terms to one side: 4 + 25y - 24y = 6

   Simplify the left side of the equation: y + 4 = 6

   Next, subtract 4 from both sides to isolate y: y + 4 - 4 = 6 - 4

   Simplify: y = 2

   So, the solution for the second equation is y = 2.

The solutions to the two equations are:

1. a = -13
2. y = 2
