Question

10+x-(2-3x)=4
10+3+x-(2-3+3)=4+3
13+x-(2-6)=7
Is that right how to solve this equation?

Answer 1

You need to get rid of the parentheses as the first step. Use the distributive property to distribute the minus sign through the parentheses.

Answer 2

So 10+3+x-2+3-3+3=4?

Answer 3

\[\begin{align}
10+x-(2-3x)=4\\
10+x+-1(2-3x)=4\\
10+x+(-1\cdot2)+(-1\cdot-3x)=4\\
10+x-2+3x=4
\end{align}\]
