Solve k=0.48-0.91/1.0-0.7approx-1.4

$$k = \frac { 0.48 - 0.91 } { 1.0 - 0.7 } \approx - 1.4$$

Solve for k

$$k = -\frac{43}{30} = -1\frac{13}{30} \approx -1.433333333$$

Steps for Solving Linear Equation

Subtract 0.91 from 0.48 to get -0.43.

$$k=\frac{-0.43}{1-0.7}$$

Subtract 0.7 from 1 to get 0.3.

$$k=\frac{-0.43}{0.3}$$

Expand \frac{-0.43}{0.3} by multiplying both numerator and the denominator by 100.

$$k=\frac{-43}{30}$$

Fraction \frac{-43}{30} can be rewritten as -\frac{43}{30} by extracting the negative sign.

$$k=-\frac{43}{30}$$

Assign k

$$k≔-\frac{43}{30}$$
