Solve 5*4+10*3+12+14*2+5x/15=11

$$\frac{ 5 \cdot 4+10 \cdot 3+12+14 \cdot 2+5x }{ 15 } = 11$$

Solve for x

$$x=15$$

Steps for Solving Linear Equation

Multiply both sides by 15.

$$5\times 4+10\times 3+12+14\times 2+5x=11\times 15$$

Multiply 5 and 4 to get 20. Multiply 10 and 3 to get 30. Multiply 14 and 2 to get 28.

$$20+30+12+28+5x=11\times 15$$

Add 20 and 30 to get 50.

$$50+12+28+5x=11\times 15$$

Add 50 and 12 to get 62.

$$62+28+5x=11\times 15$$

Add 62 and 28 to get 90.

$$90+5x=11\times 15$$

Multiply 11 and 15 to get 165.

$$90+5x=165$$

Subtract 90 from both sides.

$$5x=165-90$$

Subtract 90 from 165 to get 75.

$$5x=75$$

Divide both sides by 5.

$$x=\frac{75}{5}$$

Divide 75 by 5 to get 15.

$$x=15$$
