Add -1.5 +1.75
Plot the first addend and the sum on the number line.

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
