Answer:
x - 6 = 24
Step-by-step explanation:
1/3 x - 2 = 8
Multiply all the terms by 3
3*1/3x - 2*3 = 8*3
x - 6 = 24
when multiplying two binomials together we use the F.O.I.L. method:
First
Outer
Inner
Last
(7-3i)(2-i)
First: 7 * 2 ..... Outter: 7 * -i .... Inner: -3i * 2 ...... Last: -3i * -i
First: 14 ...... Outter= -7i ..... Inner: -6i .... Last: 3i^2
putting this together we get 14-7i-6i+2i^2
We combine like terms and end up with 2i^2-13i+14
