here are the solutions for solving for x: Question 12: Solve for x in each of the following linear equations. a) 2x + 5 = 15 Step 1: Subtract 5 from both sides of the equation to isolate the term with x. 2x + 5 - 5 = 15 - 5 2x = 10 Step 2: Divide both sides by 2 to solve for x. (2x)/(2) = (10)/(2) x = 5 The value of x is 5. b) 4x - 7 = 9 Step 1: Add 7 to both sides of the equation to isolate the term with x. 4x - 7 + 7 = 9 + 7 4x = 16 Step 2: Divide both sides by 4 to solve for x. (4x)/(4) = (16)/(4) x = 4 The value of x is 4. c) 7x - 3 = 25 Step 1: Add 3 to both sides of the equation to isolate the term with x. 7x - 3 + 3 = 25 + 3 7x = 28 Step 2: Divide both sides by 7 to solve for x. (7x)/(7) = (28)/(7) x = 4 The value of x is 4. Got more? Send 'em!
