To solve the equation |7x + 2| = 10, you first set up two equations: 7x + 2 = 10 and 7x + 2 = -10. Then, you solve each equation separately for x.
For 7x + 2 = 10: Subtract 2 from both sides to isolate 7x: 7x = 8 Divide both sides by 7 to solve for x: x = 8/7
For 7x + 2 = -10: Subtract 2 from both sides to isolate 7x: 7x = -12 Divide both sides by 7 to solve for x: x = -12/7
So, the solutions are x = 8/7 and x = -12/7.
