Solve 1980=2*22/7*15*x

$$1980=2 \times \frac{ 22 }{ 7 } \times 15 \times x$$

Solve for x

$$x=21$$

Steps for Solving Linear Equation

Express 2\times \frac{22}{7} as a single fraction.

$$1980=\frac{2\times 22}{7}\times 15x$$

Multiply 2 and 22 to get 44.

$$1980=\frac{44}{7}\times 15x$$

Express \frac{44}{7}\times 15 as a single fraction.

$$1980=\frac{44\times 15}{7}x$$

Multiply 44 and 15 to get 660.

$$1980=\frac{660}{7}x$$

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

$$\frac{660}{7}x=1980$$

Multiply both sides by \frac{7}{660}, the reciprocal of \frac{660}{7}.

$$x=1980\times \frac{7}{660}$$

Express 1980\times \frac{7}{660} as a single fraction.

$$x=\frac{1980\times 7}{660}$$

Multiply 1980 and 7 to get 13860.

$$x=\frac{13860}{660}$$

Divide 13860 by 660 to get 21.

$$x=21$$
