Question

For the function, $f\left(x\right)=5x-3$, find the value of $x$ that satisfies $f\left(x\right)=2.$

• A. $7$
• B. $2$
• C. $1$
• D. None of the above

Answer 1

The correct option is C $1$

Given:
$f\left(x\right)=5x-3$ and $f\left(x\right)=2$
Now,
$f\left(x\right)=5x-3$
$⟹2=5x-3$
Adding $3$ on both sides
$⟹2+3=5x-3+3$
$⟹5=5x$
Divide by $5$ both sides
$⟹\frac{5}{5}=x$
$⟹1=x$
$⟹x=1$
Hence, $x=1$ satisfies $f\left(x\right)=2.$
