In a previous leson, you learned that to undo multiplication by 1 + i, you would multiply by the reciprocal1/1+i.
write the complex number 1/1+i in rectangular form z = a + b where a and b are real numbers.

Alarger number is double the sum of a smaller number. the larger number is 2 less than 3 times the smaller number. if y represents the larger number and x represents the smaller number, which equations model the situation
