Solve the following equation: (5x - 4)(9x + 7) = 0 {4/5, -7/9} {-4/5, 7/9} {5/4, -9/7} {-5/4, 9/7}

Put them separately equal to 0. \[(5x - 4) = 0\] And: \[(9x+7) = 0\] Solve for x in both cases..

What do you get when you solve this: 5x - 4 = 0 Add 4 both sides and then divide by 5 both the sides and find x.. Can you do this??

so its the last one? (last option")

Don't guess it.. Solve it you will automatically have your answer.. Tell me what do you get when you add 4 both the sides to this equation: 5x - 4 = 0 Add 4 both sides and tell me what do you get??
