Answer 2

It looks like you've provided three different linear equations. To solve these equations, we need to isolate the variables (y or x) on one side of the equation. Let's solve each equation step by step:

Equation 1: -2y + 14 = 8y - 6

First, let's group the y terms on one side and the constants on the other side: -2y - 8y = -6 - 14 -10y = -20

Now, divide both sides by -10 to solve for y: y = -20 / -10 y = 2

Equation 2: -4y + 7 = 4y - 3

Similar to the first equation, let's group the y terms and constants: -4y - 4y = -3 - 7 -8y = -10

Divide both sides by -8 to solve for y: y = -10 / -8 y = 5/4 or 1.25

Equation 3: -7x + 3 = 30 - 2x

Combine the x terms and constants: -7x + 2x = 30 - 3 -5x = 27

Divide both sides by -5 to solve for x: x = 27 / -5 x = -27/5 or -5.4

So, the solutions for the given equations are:

1. y = 2
2. y = 1.25
3. x = -5.4
