Subtract.<br> (3r²s+ 4rs+2-16r²s²) - (7sr²+10-13r²s²)<br><br> Simplify answer. Do not factor
pentagon [3]

[- 3r²s² - 4sr² + 4rs - 8] is the resultant answer when we subtract the linear equation (7sr²+10-13r²s²) from (3r²s+ 4rs+2-16r²s²).

<h3>What are linear equations?</h3>
  • A linear equation in one variable is a mathematical expression for an equation with only one variable.
  • While any two real integers can represent A and B, the ambiguous variable x has just one possible value.
  • The formula is Ax + B = 0.
  • 9x + 78 = 18 is an example of a linear equation with just one variable.

So, we have:

  • (3r²s+ 4rs+2-16r²s²) - (7sr²+10-13r²s²)

Now, calculate as follows:

  • = (3r²s+ 4rs+2-16r²s²) - (7sr²+10-13r²s²)
  • = 3r²s+ 4rs+2-16r²s² - 7sr²- 10 + 13r²s²
  • = 13r²s² - 16r²s²  - 7sr² +  3r²s + 4rs - 10 + 2
  • = - 3r²s² - 4sr² + 4rs - 8

Therefore, [- 3r²s² - 4sr² + 4rs - 8] is the resultant answer when we subtract the linear equation (7sr²+10-13r²s²) from (3r²s+ 4rs+2-16r²s²).
