Solve (x*12/7)-13/10=1.4

$$( x \times 1 \frac { 2 } { 7 } ) - 1 \frac { 3 } { 10 } = 1.4$$

Solve for x

$$x=2.1$$

Steps for Solving Linear Equation

Multiply both sides of the equation by 70, the least common multiple of 7,10.

$$10x\left(1\times 7+2\right)-7\left(10+3\right)=98$$

Multiply 1 and 7 to get 7.

$$10x\left(7+2\right)-7\left(10+3\right)=98$$

Add 7 and 2 to get 9.

$$10x\times 9-7\left(10+3\right)=98$$

Multiply 10 and 9 to get 90.

$$90x-7\left(10+3\right)=98$$

Add 10 and 3 to get 13.

$$90x-7\times 13=98$$

Multiply -7 and 13 to get -91.

$$90x-91=98$$

Add 91 to both sides.

$$90x=98+91$$

Add 98 and 91 to get 189.

$$90x=189$$

Divide both sides by 90.

$$x=\frac{189}{90}$$

Reduce the fraction \frac{189}{90} to lowest terms by extracting and canceling out 9.

$$x=\frac{21}{10}$$
