Question

the solution of the equations ax+b=0is X=a/b​

Answer 1

x={-b/a}

PREMISES

y=ax+b=0

CALCULATIONS

y=ax+b=0

ax+b=0

ax+(b-b)=0-b

ax+0=-b

ax=-b

ax/a=-b/a

x=

-b/a

PROOF

If x=-b/a, then the equations

ax+b=0

a(-b/a)+b=0 (Cancel the common factor a in the denominator and adjust the numerator)

-b+b=0 and

0=0 prove the root (zero) x=-b/a of the statement ax+b=0
