A system of inequalities is shown.
y ≥ 5 y ≤ (2/3)x + 3 Graph the boundary lines of the system. Place a point on the coordinate plane to show one solution to the system.
Fred solved the equation 8(3x  7) = 6(x + 7) + 4 as shown.
Given 8(3x  7) = 6(x + 7) + 4 Step 1 24x  56 = 6x  42 + 4 Step 2 24x  56 = 6x + 46 Step 3 30x = 102 Step 4 x = 17/5 Fred made an error between step 1 and step 2. a.) Explain the error that Fred made. b.) What is the solution of the original equation?
