Answer:
the value of x=
2×-12= -24
the value of y is 3y plus 20 which equals to 23
Question one is y( Insert sign) -9
X = 4 and Y = 9. I did a complicated way of doing it so if u copy it it would look weird
First, set the equation in exponential form.
x=logbY to b^x=Y
x=log44. so x=x, b=10, Y=44
10^x=44
I know that 10^1=10, 10^2=100, and 10^1.5=31.6 so x should be between 1.5 and 2.
The answer is x=1.64.
