4.2x+3=11.82

4.2 x + 3 = 11.82

x = \frac{21}{10}

Solution steps

4.2 x + 3 = 11.82

Multiply both sides by

100

420 x + 300 = 1182

Move

300

to the right side

420 x = 882

Divide both sides by

420

x = \frac{21}{10}

\frac{a ^{2} + 11 a + 24}{a ^{3} + 27}

\frac{9}{25} a^{2} - \frac{49}{36} b^{2}

2 x^{2} - 16 x = 0

\frac{2 p}{6} - 19 = - 9
