7. Solve for x in the equation.<br>Log27(x + 7) - Log27 (x - 1) = 2/3​
babunello [35]

Answer:

x = 2

Step-by-step explanation:

log27(x + 7) - log27(x - 1) = ⅔

log27[(x + 7)/(x - 1)] = ⅔

(x + 7)/(x - 1) = 27^⅔

(x + 7)/(x - 1) = 9

x + 7 = 9(x - 1)

x + 7 = 9x - 9

8x = 16

x = 2

What is the value of x in the equation 2.5x+10=x-0.5
lisabon 2012 [21]

Answer:

x = 7

Step-by-step explanation:

Let's solve your equation step-by-step.

2.5x + 10 = x − 0.5

Step 1: Subtract x from both sides.

2.5x + 10 − x = x − 0.5 − x

1.5x + 10 = −0.5

Step 2: Subtract 10 from both sides.

1.5x +10 − 10= −0.5 − 10

1.5x = −10.5

Step 3: Divide both sides by 1.5.

1.5x/1.5 = -10.5/1.5

x = 7
