We need to isolate the dependent variable y y, we can do that by subtracting 2x 2x from both sides of the equation. y=-2x y = −2x.
Solving an Equation (How to Solve an Equation with Examples)
WebSolve: $$ 4^{x+1} = 4^9 $$ Step 1. Ignore the bases, and simply set the exponents equal to each other $$ x + 1 = 9 $$ Step 2. Solve for the variable $$ x = 9 - 1 \\ x = \fbox { 8 } $$ Check . We can verify that our answer is correct by substituting our … WebExample 3: Solve 3x = 21. Solution: Given, the equation is: 3x = 21. Since, x is multiplied by 3 in the left hand side of the equation, thus, we have to perform a division here to remove 3. Thus, dividing both sides by 3, we get; (3x)/3 = 21/3. x = 7 (Since, 3 × 7 = 21) Hence, the required solution is x = 7. dhl hershey

Gain more understanding of your homework with steps and hints guiding you from problems to answers! Wolfram Alpha Pro step-by-step solutions not only give you the answers you're looking for, but also help ... WebSolve 4 x = 17. 4 x = 17. log 4 x = log 17 . Take the common logarithm of both sides. log 4 x = log 17. x log 4 = log 17. Use the power property of logarithms to simplify the logarithm on the left. x log 4 = log 17. Divide both sides by log 4 to get x by itself. Answer. Use a calculator to evaluate the logarithms and the quotient. WebGeneral method to solve this kind (logarithm on both sides), Step 1 use the rules of logarithms to rewrite the left side and the right side of the equation to a single logarithm. Step 2 "cancel" the log. Step 3 solve the expression. Let's look at a specific ex l o g 5 x + l o g 2 3 = l o g 5 6. Step 1 rewrite both sides as single logs. cii membership discounts
