3.9x + 1.4 = 17 what is the steps

Vedmedyk [2.9K]

Answer:

$x=4$

Step-by-step explanation:

$3.9x + 1.4 = 17$

Having a decimal is not very nice to deal with, so we multiply all sides by 10 to get rid of the decimals.

$3.9x*10+1.4*10=17*10$

$39x+14=170$

Subtract 14 from both sides:

$39x+14-14=170-14$

$39x=156$

Divide both sides by 39:

$\frac{39x}{39}=\frac{156}{39}$

$x=4$
