Zahra wants the equation below to have an infinite number of solutions when the missing number is placed in the box. _(x-3)+2x=-( x-5)+4 Which number should she place in the box?
1.)–3
2.)–1
3.)1
4.)3
In order for an equation to have an infinite number of answers, the simplified equation should be x=x. In evaluating the above equation, -3 inserted in the box results in this simplified equation. The answer is therefor #1: -3
