dividing decimals: 1614.62/ 3.8

If the divisor is not a whole number, move decimal point to right to make it a whole number and move decimal point in dividend the same number of places. Divide as usual. Keep dividing until the answer terminates or repeats. Put decimal point directly above decimal point in the dividend. 424.9

### Subject: Basic Math

Solve the system of linear equations. -2x + 3y = 8 3x - y = -5

multiply all terms in the second equation by 3 -2x + 3y = 8 9x - 3y = -15 add the two equations 7x = -7 divide by 7 on both sides x = -1 substitute x by -1 in the first equation -2(-1) + 3y = 8 solve the above equation for y 2 + 3y = 8 3y = 6 y = 2 write the solution to the system as an ordered pair (-1,2)
