2x + 7 = x + 3
First, subtract x from both sides. / Your problem should look like: [tex]2x + 7 - x = 3[/tex]
Second, simplify 2x + 7 - x to x + 7. / Your problem should look like: [tex]x + 7 = 3[/tex]
Third, subtract 7 from both sides. / Your problem should look like: [tex]x = 3 - 7[/tex]
Fourth, subtract 3 - 7 to get -4. / Your problem should look like: [tex]x = -4[/tex]
Answer: x = -4
