- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
r = 4s
r = 1/2s + 7
<u>Step 2: Solve for </u><em><u>s</u></em>
<em>Substitution</em>
- Substitute in <em>r</em>: 4s = 1/2s + 7
- Subtract 1/2s on both sides: 7/2s = 7
- Divide 7/2 on both sides: s = 2
<u>Step 3: Solve for </u><em><u>r</u></em>
- Define equation: r = 4s
- Substitute in <em>s</em>: r = 4(2)
- Multiply: r = 8
Answer:
The answer to your question is: x = 4.44
Step-by-step explanation:
Data
ln(x + 1) − ln(2) = 1
In (x + 1)/2 = 1
(x + 1) / 2 = e¹
x + 1 = 2 (2.7183)
x = 5.44 - 1
x = 4.44
8*4 = 32
Now, we need to solve this:-
32 = (?*7) - (?*3)
32=8*7 - 8*3
32= 56 - 24
32 = 32
So our equation is:-
8*4 = (8*7) - (8*3)
Mathematics and science go hand in hand. The branches of science which include: Physics, astronomy, chemistry, biology, etc. In all these fields you will find that you will have to use the mathematical principles and formulae to solve the numerical problems. So, science needs maths but maths does not need science.
