Solve 0=x*6+6*9+3*8-6*7+3*9

$$0=x \times 6+6 \times 9+3 \times 8-6 \times 7+3 \times 9$$

Solve for x

$$x = -\frac{21}{2} = -10\frac{1}{2} = -10.5$$

Steps for Solving Linear Equation

Multiply 6 and 9 to get 54. Multiply 3 and 8 to get 24.

$$0=x\times 6+54+24-6\times 7+3\times 9$$

Add 54 and 24 to get 78.

$$0=x\times 6+78-6\times 7+3\times 9$$

Multiply 6 and 7 to get 42.

$$0=x\times 6+78-42+3\times 9$$

Subtract 42 from 78 to get 36.

$$0=x\times 6+36+3\times 9$$

Multiply 3 and 9 to get 27.

$$0=x\times 6+36+27$$

Add 36 and 27 to get 63.

$$0=x\times 6+63$$

Swap sides so that all variable terms are on the left hand side.

$$x\times 6+63=0$$

Subtract 63 from both sides. Anything subtracted from zero gives its negation.

$$x\times 6=-63$$

Divide both sides by 6.

$$x=\frac{-63}{6}$$

Reduce the fraction \frac{-63}{6} to lowest terms by extracting and canceling out 3.

$$x=-\frac{21}{2}$$
