What is the value of x in the equation 1/2x-3/4=3/8-5/8x?

Vladimir [108]

Answer:

x = 1

Step-by-step explanation:

1/2x - 3/4 = 3/8 - 5/8x

The LCD is 8. Lets change every fraction to a denominator of 8.

4/8x - 6/8 = 3/8 - 5/8x

Now multiply both sides by 8.

4x - 6 = 3 - 5x

Add 5x to both sides. Add 6 to both sides.

9x = 9

Divide both sides by 9.

x = 1

velikii [3]

Answer:

see explanation

Step-by-step explanation:

Using the rules of exponents

$a^{-m}$ ⇔ $\frac{1}{a^{m} }$ and $a^{0}$ = 1

Substitute the values of x into $4^{-x}$

x = 0 → $4^{0}$ = 1 ⇒ a = 1

x = 2 → $4^{-2}$ = $\frac{1}{4^{2} }$ = $\frac{1}{16}$ , hence

b = $\frac{1}{16}$

x = 4 → $4^{-4}$ = $\frac{1}{4^{4} }$ = $\frac{1}{256}$ , hence

c = $\frac{1}{256}$

(7 + X) x 8 - 4 x X = 56

devlian [24]

Answer:

12 1/4

Step-by-step explanation:

(7 + X) × 8 - 4 × X = 56

7 + X × 8 - 4 × X = 56

7 + 8X - 4 × X = 56

7 + 8X - 4X = 56

7 + 4X = 56

4X = 56 - 7

X = 49/4

X = 12 1/4
