Question

Evaluate $\mathrm{x}$ in $-89-4\mathrm{x}=-10\mathrm{x}+25$

Answer 1

To find the value of $\mathrm{x}$ in $-89-4\mathrm{x}=-10\mathrm{x}+25$, we get

Transfer the variable and constant terms on two different sides ,we get

$-4\mathrm{x}+10\mathrm{x}=25+89$ (change in sides changes the sign and binary operations of the terms)

$6\mathrm{x}=114$

⇒ $\mathrm{x}=\frac{114}{6}$ (change in sides changes the sign and binary operations of the terms)

$\mathrm{x}=19$

Thus $\mathrm{x}=19$
