How did James watt contribute to the industrial revolution

Explanation:

James Watt was an 18th-century inventor and instrument maker. Although Watt invented and improved a number of industrial technologies, he is best remembered for his improvements to the steam engine.

Watt aided the Industrial Revolution even more when he discovered a way to make a steam engine turn in circles. This made it possible to use steam engines for purposes other than pumping water out of coal mines. As a result, Watt aided the Industrial Revolution by making steam power far more useful for driving machinery.

In clearer terms, James Watt aided the Industrial Revolution by improving the Newcomen steam engine, resulting in a new, more efficient engine.

Hope this helps and if it does, don't be afraid to give my answer a "Thanks" and maybe a Brainliest if it's correct?  

simplify brackets

8 - 2a - 7 = a + 40

simplify 8 - 2a - 7 to -2a + 1

-2a + 1 = a + 40

add 2a to both sides

1 = a + 40 + 2a

simplify a + 40 + 2a to 3a + 40

1 = 3a + 40

subtract 40 from both sides

1 - 40 = 3a

simplify 1 - 40 o -39

-39 = 3a

divide both sides by 3

-39/3 = a

simplify 39/3 to 13

-13 = a

switch sides

a = -13
