Here are the solutions to the problems: Problem 2: Find the value of x if 3x + 4 = 19. Step 1: Subtract 4 from both sides of the equation to isolate the term with x. 3x + 4 - 4 = 19 - 4 3x = 15 Step 2: Divide both sides by 3 to solve for x. (3x)/(3) = (15)/(3) x = 5 The value of x is 5. Problem 3: Find the value of y when 2y - 7 = 21. Step 1: Add 7 to both sides of the equation to isolate the term with y. 2y - 7 + 7 = 21 + 7 2y = 28 Step 2: Divide both sides by 2 to solve for y. (2y)/(2) = (28)/(2) y = 14 The value of y is 14.
