To solve the two equations simultaneously using the substitution method we need to rearrange one of the equation to make either
or
the subject.
We can try in turn rearranging both equations and see which unknown term would have been easier to solve first
Equation
Making
the subject
, dividing each term by 2
⇒ (Option 1)
Making
the subject
, multiply each term by 8 gives
⇒ (Option 2)
Equation
Making
the subject
, divide each term by 3
⇒ (Option 3)
Making
the subject
, divide each term by 8
⇒ (Option 4)
From all the possibilities of rearranged term, the most efficient option would have been the first option, from equation
with
as the subject,
Answer:
2(1)²−1= 1
2(2)²−1= 7
2(3)²−1= 17
2(4)²−1= 31
2(5)²−1= 49

Answer:
no, the calculator is not broken
Step-by-step explanation:
Answer:
x = -52
Step-by-step explanation:
1/3x-2/3=-18
Multiply each side by 3 to clear the fractions
3(1/3x-2/3)=-18*3
x - 2 = -54
Add 2 to each side
x-2+2 = -54+2
x = -52
Answer:
-14c
Step-by-step explanation:
I’m using the actual values 1F = -17C so just times that by 5.4
