Answer:
Step-by-step explanation:
The given equations are:
2a+7b=0 and 3a-5b=31
Statement Reason
1. 10a+35b=0, 21a-35b=217 (Multiply first equation by 5 and second by 7)
2. 31a=217 (Adding both the equations)
3. a=7 (Dividing both sides by 31)
4. 2(7)+7b=0 (Substituting a=7 in first equation)
5.14+7b=0 (solving step 4)
6. 7b=-14 (Subtracting 14 on both sides)
Answer:
x = -3.5
Step-by-step explanation:
-2(5x – 3) = 41
-10x + 6 = 41
-10x + 6 - 6 = 41 - 6
-10x/-10 = 35/-10
x = -3.5
Answer:
x⁶/-3
Step-by-step explanation:
1 / (-3 / x⁶ )
= 1 . (x⁶/-3)
=x⁶/-3
