Answer 2

Sure, let's solve these equations step by step.

Equation 1: $9x - 26 = 30 - 5x$

First, let's simplify the equation by combining like terms. Add $5x$ to both sides:

$9x + 5x - 26 = 30$

$14x - 26 = 30$

Next, isolate $14x$ by adding 26 to both sides:

$14x = 56$

Finally, divide by 14 to solve for $x$:

$x = 4$

Equation 2: $0.9x - 7.4 = 0.4 + 4.3x$

First, let's simplify the equation by combining like terms. Subtract $0.4$ from both sides:

$0.9x - 7.4 - 0.4 = 4.3x$

$0.9x - 7.8 = 4.3x$

Next, subtract $0.9x$ from both sides:

$-7.8 = 3.4x$

Finally, divide by $3.4$ to solve for $x$:

$x \approx -2.29$ (rounded to two decimal places)

So, the solutions are $x = 4$ for the first equation and $x \approx -2.29$ for the second equation.
