We simplify this expression using the PEMDAS rule
(Parentheses > Exponents > Mult and Div > Add and Subtract)

$2 x + 5 (6 x - 4) + 1$ $color(red)(2x +5(6x-4)+ 1$ is the expression given to us.

We Multiply terms before we perform the Addition

$= 2 x + (5 \cdot 6 x) + (5 \cdot - 4) + 1$ $= 2x +(5*6x)+(5*-4)+ 1$
( We used the Distributive Property of Multiplication)

$= 2 x + 30 x - 20 + 1$ $= 2x + 30x - 20 + 1$

$= (2 x + 30 x) - (20 - 1)$ $= (2x + 30x) - (20 - 1)$

$= 32 x - 19$ $color(green)( = 32x - 19$
