We want 4/5 of a number to be 144. This means that

$\dfrac{4}{5} \cdot x = 144$

Multiplying both sides by 5/4, we have

$x = \dfrac{144\cdot 5}{4} = 180$

2(x + 2) + 2 = 2(x + 3) + 1

Maslowich

Answer:

No solution

Step-by-step explanation:

5(x + 4) – x = 4(x + 5) – 1

x = ?

Solution:

5(x+4)−x=4(x+5)−1

Apply Distributive property:

(5)(x)+(5)(4)−x=(4)(x)+(4)(5)−1
5x+20−x=4x+20−1

Combine Like Terms:

(5x−x)+(20)=(4x)+(20−1)
4x+20=4x+19
4x+20=4x+19

Subtract 4x from both sides:

4x+20−4x=4x+19−4x
20=19

Subtract 20 from both sides:

20−20=19−20
0=−1

There isn't any solutions.
