Liam made a deposit of $31,050 into an account with a rate of 20%. How long should he leave the money into the account if he wants to earn $93,150 in interest?

You move the constant to the right side and change its sign to be 9z= -6 -8. that’s the first step.the second step would be calculate the difference of -8-6 to get -14. you equation should now be 9z=-14the last step is to divide both sides by 9 to get z=-14/9hope this
