8x - 3 = 15x + 18
First, subtract 8x from both sides. / Your problem should look like: \(-3 = 15x + 18 - 8x\)
Second, simplify 15x + 18 - 8x to 7x + 18. / Your problem should look like: \(-3 = 7x + 18\)
Third, subtract 18 from both sides. / Your problem should look like: \(-3 - 18 = 7x\)
Fourth, subtract -3 - 18 to get -21. / Your problem should look like: \(-21 = 7x\)
Fifth, divide both sides by 7. / Your problem should look like:\(-\frac{21}{7}\) = x
Sixth, simplify \(\frac{21}{7}\) to 3. / Your problem should look like: \(-3 = x\)
Seventh, switch sides. / Your problem should look like: \(x = -3\)
Answer: x = -3
