Question

What is the solution to this 2x+1+x=3(x-2)+7

Answer 1

infinite solutions

x is all real numbers

Explanation:

2x+1+x=3(x-2)+7

Distribute

2x+1 +x = 3x -6+7

Combine like terms

3x+1 = 3x+1

Subtract 3x from each side

3x-3x+1 = 3x-3x+1

1=1

This is always true, so it doesn't matter what value we put in for x

X is all real numbers
