x = \frac{772}{155}

Decimal Notation

x = 4.98064 \dots

Solution steps

4.2 (5 x - 7) - 2.5 (2 - 4 x) = 120

Multiply both sides by

10

42 (5 x - 7) - 25 (2 - 4 x) = 1200

Expand

42 (5 x - 7) - 25 (2 - 4 x) : 310 x - 344

310 x - 344 = 1200

Move

344

to the right side

310 x = 1544

Divide both sides by

310

x = \frac{772}{155}

\frac{x}{2} - \frac{6 - x}{4} = x + 1

x, x y^{2} - x + 3 y^{2} + 1 = 0

\frac{( 3 x + 2 )}{5} = 2

x, y = f + 3

2 x + 5 x - 30 = 180
