Answer:

$\displaystyle\blue{5x+3=78-4\quad :\quad x=\frac{71}{5}\quad \left(\mathrm{Decimal}:\quad x=14.2\right)}$

Step-by-step explanation:

$5x+3=78-4$

$\gray{\mathrm{Subtract\:the\:numbers:}\:78-4=74}$

$5x+3=74$

$\gray{\mathrm{Subtract\:}3\mathrm{\:from\:both\:sides}}$

$5x+3-3=74-3$

$\gray{\mathrm{Simplify}}$

$5x=71$

$\gray{\mathrm{Divide\:both\:sides\:by\:}5}$

$\displaystyle\frac{5x}{5}=\frac{71}{5}$

$\gray{\mathrm{Simplify}}$

$\displaystyle x=\frac{71}{5}$
