Answer:

see explanation

Step-by-step explanation:

Vertical angles are congruent, hence

2z + 43 = - 10z + 25 ( add 10z to both sides )

12z + 43 = 25 ( subtract 43 from both sides )

12z = - 18 ( divide both sides by 12 )

z = $\frac{-18}{12}$ = - $\frac{3}{2}$

What is 1/6x=4 in solving equations with rational coefficients

Debora [2.8K]

To solve an equation with a rational (fraction) coefficient you need to multiply both sides of the equation by the reciprocal (invert the fraction - flip it).

$\frac{1}{6}x =4$ The reciprocal of 1/6 is 6/1 or 6
$6( \frac{1}{6} x)= 6(4)$ The product of reciprocals equals 1
1x = 24
x = 24
