Answer 2

It seems like you've provided three different linear equations with one variable each. To solve these equations, we'll isolate the variable on one side of the equation. Here's how you can solve each equation step by step:

1. $0.8x - 9x = 3x + 132$

Combine like terms on both sides: $-8.2x = 3x + 132$

Add $8.2x$ to both sides: $0 = 11.2x + 132$

Subtract 132 from both sides: $-132 = 11.2x$

Divide both sides by 11.2: $x = -11.7857$

2. $2.7m + 4.7 = 2.3m + 9.53$

Subtract $2.3m$ from both sides: $0.4m + 4.7 = 9.53$

Subtract 4.7 from both sides: $0.4m = 4.83$

Divide both sides by 0.4: $m = 12.075$

3. $1.3y - 14.2 = 11.3 - 3.8y$

Add $3.8y$ to both sides: $5.1y - 14.2 = 11.3$

Add 14.2 to both sides: $5.1y = 25.5$

Divide both sides by 5.1: $y = 5$

So, the solutions for the given equations are:

1. $x = -11.7857$
2. $m = 12.075$
3. $y = 5$
