Solve 4+144+32-120+72+lambda[74+16-24]=0

$$4 + 144 + 32 - 120 + 72 + \lambda [ 74 + 16 - 24 ] = 0$$

Solve for λ

$$\lambda =-2$$

Steps for Solving Linear Equation

Add 4 and 144 to get 148.

$$148+32-120+72+\lambda \left(74+16-24\right)=0$$

Add 148 and 32 to get 180.

$$180-120+72+\lambda \left(74+16-24\right)=0$$

Subtract 120 from 180 to get 60.

$$60+72+\lambda \left(74+16-24\right)=0$$

Add 60 and 72 to get 132.

$$132+\lambda \left(74+16-24\right)=0$$

Add 74 and 16 to get 90.

$$132+\lambda \left(90-24\right)=0$$

Subtract 24 from 90 to get 66.

$$132+\lambda \times 66=0$$

Subtract 132 from both sides. Anything subtracted from zero gives its negation.

$$\lambda \times 66=-132$$

Divide both sides by 66.

$$\lambda =\frac{-132}{66}$$

Divide -132 by 66 to get -2.

$$\lambda =-2$$
