Solve 5*4left(x+3right)=4left(x+3right)-3

$$5 \cdot 4 \left( x+3 \right) = 4 \left( x+3 \right) -3$$

Solve for x

$$x = -\frac{51}{16} = -3\frac{3}{16} = -3.1875$$

Steps for Solving Linear Equation

Multiply 5 and 4 to get 20.

$$20\left(x+3\right)=4\left(x+3\right)-3$$

Use the distributive property to multiply 20 by x+3.

$$20x+60=4\left(x+3\right)-3$$

Use the distributive property to multiply 4 by x+3.

$$20x+60=4x+12-3$$

Subtract 3 from 12 to get 9.

$$20x+60=4x+9$$

Subtract 4x from both sides.

$$20x+60-4x=9$$

Combine 20x and -4x to get 16x.

$$16x+60=9$$

Subtract 60 from both sides.

$$16x=9-60$$

Subtract 60 from 9 to get -51.

$$16x=-51$$

Divide both sides by 16.

$$x=\frac{-51}{16}$$

Fraction \frac{-51}{16} can be rewritten as -\frac{51}{16} by extracting the negative sign.

$$x=-\frac{51}{16}$$
