Question

solve \\(\frac{x + 15}{10} = \frac{2}{5}\\). \
\
a) 19\
\
\
\
b) -13\
\
\
\
c) 1\
\
\
\
d) -11

Explanation:

Step1: Cross-multiply to eliminate fractions

$$5(x+15) = 2 \times 10$$

Step2: Simplify both sides

$$5x + 75 = 20$$

Step3: Isolate the term with $x$

$$5x = 20 - 75$$
$$5x = -55$$

Step4: Solve for $x$

$$x = \frac{-55}{5} = -11$$

Answer:

D) -11
