Question

Solve for x, 2x + 1 = 4

Answer 1

Answer:

$2 x + 1 = 4 \quad : \quad x = \dfrac{ 3 }{ 2 } \quad \left(\mathrm{ D e c i m a l } : \quad x = 1 . 5 \right)$

Step-by-step explanation:

$2 x + 1 = 4$

$\gray{\mathrm{ S u b t r a c t \: } 1 \mathrm{ \: f r o m \: b o t h \: s i d e s }}$

$2 x + 1 - 1 = 4 - 1$

$\gray{\mathrm{ S i m p l i f y }}$

$2 x = 3$

$\gray{\mathrm{ D i v i d e \: b o t h \: s i d e s \: b y \: } 2 }$

$\dfrac{ 2 x }{ 2 } = \dfrac{ 3 }{ 2 }$

$\gray{\mathrm{ S i m p l i f y }}$

$x = \dfrac{ 3 }{ 2 }$

Answer 2

here's your answer mate

→2x + 1 = 4
→ 2x = 4 - 1
→ x = 3/2
→ x= 1.5
