Answer: (-1,2)
Steps:
Solve by elimination
Multiply the first equation by 2 to make the coefficients of x in both equations the same
2(x+2y=3)
2x+4y=6
Then line them up and subtract
2x+y=0
-2x+4y=6
= -3y=-6
Divide both sides by -3 to isolate y
y=2
Then substitute 2 for y into one of the equations to find x.
x+2(2)=3
x+4=3
x=-1
22 in long left cause if you just subtract it<span />
There are 100 centimeters in one meter
therefore .1 meters = 10 centimeters
.01 meters = 1 centimeter
to convert form centimeters to meters you will move the decimal to the left 2 times starting from the far most right digit.
(3-4i)(5+6i)
15+18i-20i-24i^2
15+18i-20i+24=
39-2i
