Solution for (2e-3)*(7+5e)=(10e-4)(e-3) equation:


Simplifying
(2e + -3)(7 + 5e) = (10e + -4)(e + -3)

Reorder the terms:
(-3 + 2e)(7 + 5e) = (10e + -4)(e + -3)

Multiply (-3 + 2e) * (7 + 5e)
(-3(7 + 5e) + 2e * (7 + 5e)) = (10e + -4)(e + -3)
((7 * -3 + 5e * -3) + 2e * (7 + 5e)) = (10e + -4)(e + -3)
((-21 + -15e) + 2e * (7 + 5e)) = (10e + -4)(e + -3)
(-21 + -15e + (7 * 2e + 5e * 2e)) = (10e + -4)(e + -3)
(-21 + -15e + (14e + 10e2)) = (10e + -4)(e + -3)

Combine like terms: -15e + 14e = -1e
(-21 + -1e + 10e2) = (10e + -4)(e + -3)

Reorder the terms:
-21 + -1e + 10e2 = (-4 + 10e)(e + -3)

Reorder the terms:
-21 + -1e + 10e2 = (-4 + 10e)(-3 + e)

Multiply (-4 + 10e) * (-3 + e)
-21 + -1e + 10e2 = (-4(-3 + e) + 10e * (-3 + e))
-21 + -1e + 10e2 = ((-3 * -4 + e * -4) + 10e * (-3 + e))
-21 + -1e + 10e2 = ((12 + -4e) + 10e * (-3 + e))
-21 + -1e + 10e2 = (12 + -4e + (-3 * 10e + e * 10e))
-21 + -1e + 10e2 = (12 + -4e + (-30e + 10e2))

Combine like terms: -4e + -30e = -34e
-21 + -1e + 10e2 = (12 + -34e + 10e2)

Add '-10e2' to each side of the equation.
-21 + -1e + 10e2 + -10e2 = 12 + -34e + 10e2 + -10e2

Combine like terms: 10e2 + -10e2 = 0
-21 + -1e + 0 = 12 + -34e + 10e2 + -10e2
-21 + -1e = 12 + -34e + 10e2 + -10e2

Combine like terms: 10e2 + -10e2 = 0
-21 + -1e = 12 + -34e + 0
-21 + -1e = 12 + -34e

Solving
-21 + -1e = 12 + -34e

Solving for variable 'e'.

Move all terms containing e to the left, all other terms to the right.
