Determine the value of ¢ in the given equation.
$$3,000 — a = 1,096$$ Write the equation
$$3,000—a— 3,000 = 1,096—3,000$$ Subtract 3,000 from both sides
$$-a=-1904$$ Simplify
$$\displaystyle-{1}\frac{{a}}{{-{{1}}}}=-\frac{{1904}}{{-{{1}}}}$$ Divide both sides by —1
$$a=1904$$ Simplify
Check by substituting the value of $$\alpha$$ to the original equation.
$$3,000— a = 1,096$$ Write the equation
$$3,000— 1,904 = 1,096$$ Substitute the value of a
$$1,096 = 1,096$$ The statement is true
