Answer 2

To solve the equations, let's first get rid of the decimal points by multiplying each equation by an appropriate factor so that all coefficients become integers. We can achieve this by multiplying each equation by 10. Here are the modified equations:

1. $30x - 18 = 52 - 33x$

2. $-84 - 75x = 125x + 116$

Now, we'll isolate the variable $x$ in each equation:

1. $30x + 33x = 52 + 18$

Combine like terms:

$63x = 70$

Divide by 63 to solve for $x$:

$x = \frac{70}{63} = \frac{10}{9}$

2. $-75x - 125x = 116 + 84$

Combine like terms:

$-200x = 200$

Divide by -200 to solve for $x$:

$x = \frac{200}{-200} = -1$

So, the solution to the system of equations is $x = \frac{10}{9}$ and $x = -1$.
