Answer:
Please see attached picture for full solution.
Step-by-step explanation:
You should multiply the number outside the bracket with each term, with their symbols (plus/minus), in the bracket.
6x + 7 = 13x - 9
7 + 9 = 13x - 6x
16 = 7x
16/7 = x....or 2 2/7 = x
Answer:
6x +10
Step-by-step explanation:
Perimeter = 2*(length + width)
= 2* (x+6 + 2x-1)
=2*(3x +5)
=2*3x + 2*5
=6x + 10
Answer:
5x(−7yz+4y+3)
Step-by-step explanation:
(2 − 3i) + (x + yi) = 6
We add the left hand side
(2+x) + (-3+y)i = 6
6 can be written in a+ib
6 can be written as 6 + 0i
(2+x) + (-3+y)i = 6 +0i
Now we frame 2 equations
2 + x= 6
-3 + y =0
Solve the first equation
2 + x = 6
Subtract 2 from both sides
x = 4
solve the second equation
-3 + y =0
Add 3 on both sides
y= 3
So x+yi is 4+3i
