Understand and Identify Bases: Understand the equation and identify similar bases.The equation is 9x+1+1=10(3x). We notice that 9 is a power of 3, specifically 9=32. This will allow us to rewrite the equation with a common base.
Rewrite and Simplify Equation: Rewrite 9 as 32 and simplify the equation.9x+1 can be written as (32)(x+1). Using the power of a power rule, we get 32(x+1). The equation now looks like this:32(x+1)+1=10(3x)
Expand Exponent: Expand the exponent in the term 32(x+1).2(x+1) is equal to 2x+2. So, we rewrite the equation as:32x+2+1=10(3x)
Divide and Simplify: Divide both sides of the equation by 3x to simplify.(32x+2)/(3x)+1/(3x)=10Using the quotient of powers rule, we get:32x+2−x+1/(3x)=10This simplifies to:3x+2+1/(3x)=10
Recognize Limitations: Recognize that the equation cannot be simplified further algebraically. At this point, we realize that the equation 3(x+2)+3x1=10 does not lend itself to further algebraic manipulation. We need to use another method, such as trial and error, graphing, or a numerical method to find the value of x.
Trial and Error Solution: Use trial and error or a numerical method to find the value of x. Since the problem does not specify a method, we will use trial and error. We know that 30=1, so let's try x=0: 3(0+2)+301=32+1=9+1=1010=10 This is true, so x=0 is a solution.
