John wants to move from point A to point B. To avoid the pond, he must walk 36 south and 49 east. However, he wants to go through the pond in order to save time. To the nearest meter, calculate how many meters would be saved if John rows a boat across the pond?

I'm not sure sorry that i couldn't

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
