Answer 3

To solve the equation $4.2x + 1.7x - 1.5x = 7.9$, you can combine like terms on the left side of the equation and then solve for $x$.

1. Combine the $x$ terms:

$(4.2x + 1.7x - 1.5x) = 4.2x + 1.7x - 1.5x = 4.4x$

Now, the equation becomes:

$4.4x = 7.9$

2. To solve for $x$, divide both sides of the equation by 4.4:

$\frac{4.4x}{4.4} = \frac{7.9}{4.4}$

Simplify:

$x = \frac{7.9}{4.4}$

You can further simplify the fraction or express it as a decimal for a numerical answer.
