Question

Sort the following algebraic equations according to the increasing values of their unknowns.

• A. $x÷3=9$
• B. $y+5=15$
• C. $z-8=16$
• D. $m\times 10=90$

Answer 1

A. $m\times 10=90$

Dividing by $10$,

$\frac{10\times m}{10}=\frac{90}{10}=9$

$\Rightarrow m=9$

The value of '$m$' is 9.

B. $y+5=15$

Subtracting $5$ from both the sides:

$y+5-5=15-5=10$

The value of '$y$' is $10$.

C. $z-8=16$

Adding $8$ on both sides,

$z-8+8=16+8=24$

The value of '$z$' is $24$.

D. $x÷3=9$

Multiplying by $3$,

$\frac{3\times x}{3}=9\times 3=27$

The value of '$x$' is $27$.

The increasing order of the values of unknowns:
$m<y<z<x$
