0.3(z-4)=15

0.3 (z - 4) = 15

z = 54

Solution steps

0.3 (z - 4) = 15

Multiply both sides by

3 (z - 4) = 150

Divide both sides by

3

z - 4 = 50

Move

to the right side

z = 54

4 (- \frac{3}{8})

\frac{5 x + 7}{3} = \frac{x - 1}{4}

8 + 3 \cdot x = 2^{2} + x^{2}

x^{2} + 6 x - 4 = 36

\frac{x + 3}{x - 5} < 0
