Solve -2a-4*(a-5)=-3*(-8)

$$- 2 a - 4 \times ( a - 5 ) = - 3 \times ( - 8 )$$

Solve for a

$$a=-\frac{2}{3}\approx -0.666666667$$

Steps for Solving Linear Equation

Use the distributive property to multiply -4 by a-5.

$$-2a-4a+20=-3\left(-8\right)$$

Combine -2a and -4a to get -6a.

$$-6a+20=-3\left(-8\right)$$

Multiply -3 and -8 to get 24.

$$-6a+20=24$$

Subtract 20 from both sides.

$$-6a=24-20$$

Subtract 20 from 24 to get 4.

$$-6a=4$$

Divide both sides by -6.

$$a=\frac{4}{-6}$$

Reduce the fraction \frac{4}{-6} to lowest terms by extracting and canceling out 2.

$$a=-\frac{2}{3}$$
