Answer:
x=-3/19
y=39/19
Step-by-step explanation:
the equations can be written as the following system
If the second equation is multiplied by 3/2 it will become -18x+3y=9
If that equation is then subtracted with the first you will obtain the following
-19x=3, it means x=-3/19
The other variable is obtained by substituting the new value for x in the first equationx+3y=6, thus we obtain that y=39/19
Answer:
The answer to your question is log₁₀ x + b = a
Step-by-step explanation:
General formula
Logarithmic function Exponential function
log ₐ b = c
a = antilogaritm c = exponent
b = base b = base
c = logaritm a = power
In your problem
10 = base
a = exponent
x + b = power
Exponential function log₁₀ x + b = a
