Answer:
1) 3a + 3b
2) 3a + 4b
3) 5a +3c
4) 3a + 3b
5) 7a + 2b
6) 4a + 4c
7) 7c +4d
8) 2a + 6b
Step-by-step explanation:
1) 2a + a + 3b = 3a + 3b
2) 2a + 2b + a + 2b = 3a + 4b
3) 3a + 2c + 2a + c = 5a +3c
4) a + 2b + 2a + b = 3a + 3b
5) 4a + b + 3a + b = 7a + 2b
6) 3a + 2c + 2c + a = 4a + 4c
7) 3d + 2c + d + 5c = 7c +4d
8) a + 2b + a + 3b + b = 2a + 6b
Answer:
6-11i
Step-by-step explanation:
(2 + 7i) - (6 + 8i) + (10 - 10i)
Distribute the minus sign
(2 + 7i) - 6 - 8i + (10 - 10i)
Combine like terms
2-6 +10 +7i-8i-10i
6 -11i
Step-by-step explanation:
-7(1+3x) = 4 + 5x
-7 - 21x = 4 + 5x
(get all the variables on one side. Don't forget to change the signs)
-7-4 = 5x + 21x
-11 = 26x
(divide both sides by the coefficient [26])
26x/26= -11/26
x = -11/26
