Question

Solve equation for indicated variable:

g= -2 x + 1 , for x

Answer 1

Answer:

-(g-1)/2=x

Step-by-step explanation:

g=-2x+1

subtract one from both sides

g-1=-2x

divide both sides by -2

(g-1)/-2=x

Answer 2

Answer:

$\large\boxed{x=\dfrac{1-g}{2}}$

Step-by-step explanation:

$g=-2x+1\\\\\Downarrow\\\\-2x+1=g\qquad\text{subtract 1 from both sides}\\\\-2x+1-1=g-1\\\\-2x=g-1\qquad\text{divide both sides by (-2)}\\\\\dfrac{-2x}{-2}=\dfrac{g-1}{-2}\\\\x=\dfrac{-(1-g)}{-2}\\\\x=\dfrac{1-g}{2}$
