Answer:
The GCF for the numerical part is 4 . The factors for x2
Step-by-step explanation:
2(b + 3c) → We first need to simplify this.
Simplify.
2b + 6c
1st Option :
3(b + 2c)
Simplify.
3b + 6c
This is INCORRECT, as it is not equal to 2b + 6c.
2nd Option :
(b + 3c) + (b + 3c)
Simplify.
2b + 6c
This is CORRECT because 2b+6c = 2b+6c
(b + 3c) + (b + 3c) → Answer
~Hope I helped!~
There is one solution: w=3
-2a + 3b = 9 / x 2;
-4a + 6b = 18;
Then, -4a + 6b = 18
+4a - 2b = 3
__________________(+)
We obtain 4b = 21;
b = 21/4;
-2a + 63/4 = 9;
-8a + 63 = 36;
-8a = - 27;
a = 27/8 ;
