Solve -2(6+7p)-7(p+7)=-40

$$- 2 ( 6 + 7 p ) - 7 ( p + 7 ) = - 40$$

Solve for p

$$p=-1$$

Steps for Solving Linear Equation

Use the distributive property to multiply -2 by 6+7p.

$$-12-14p-7\left(p+7\right)=-40$$

Use the distributive property to multiply -7 by p+7.

$$-12-14p-7p-49=-40$$

Combine -14p and -7p to get -21p.

$$-12-21p-49=-40$$

Subtract 49 from -12 to get -61.

$$-61-21p=-40$$

Add 61 to both sides.

$$-21p=-40+61$$

Add -40 and 61 to get 21.

$$-21p=21$$

Divide both sides by -21.

$$p=\frac{21}{-21}$$

Divide 21 by -21 to get -1.

$$p=-1$$
