Solve the equation for x. 2 3 x −1 9 x + 5 = 20

step 1: simplify both sides of the equation.

23x − 19x + 5 = 20

23x + − 19x + 5 = 20

(23x + − 19x) + (5) = 20 (combine like terms)

4x + 5 =20

4x+5=20

step 2:

step 2: subtract 5 from both sides.

4x + 5 − 5 = 20 − 5

4x = 15

step 3: divide both sides by 4.

answer: x =

in decimal form: 3.75

step-by-step explanation:

the first 5 right here the next 5 i will upload as separate question

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
