Answer 2

Sure, I can help you solve the equation $0.7 - 2c = 3c + 1.7$. Let's solve it step by step.

First, let's simplify the equation by combining like terms.

$0.7 - 2c = 3c + 1.7$

Combine the constant terms on the right side:

$0.7 - 2c = 3c + 1.7$

Now, let's move all the $c$ terms to one side and the constant terms to the other side. To do this, let's subtract $3c$ from both sides and subtract $0.7$ from both sides:

$-2c - 3c = 1.7 - 0.7$

$-5c = 1$

Now, divide both sides by $-5$ to solve for $c$:

$c = -\frac{1}{5}$

So, the solution to the equation $0.7 - 2c = 3c + 1.7$ is $c = -\frac{1}{5}$.
