33,600

Step-by-step explanation:

take -4200 and multiply it by 8. You'd do this since the equation to get -4200 is

x(1/8) = -4200

multiply both sides by 8 to get rid of the fraction and you get x=33,600

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
