Answer:
[tex]1)3x = 15 \\ \\ x = \frac{15}{3} \\ \\ x = 5 \\ \\ 2)56 = - 8x \\ \\ x = \frac{56}{ - 8} \\ \\ x = - 7 \\ \\ 3) \frac{x}{4} = 20 \\ \\ x = 20 \times 4 \\ \\ x = 20 \\ \\ 4)10 = \frac{x}{ - 2} \\ \\ 10 \times ( - 2) = x \\ \\ x = - 20 \\ \\ 5) - 6y = - 48 \\ \\ y = \frac{ - 48}{ - 6} \\ \\ y = 8[/tex]
