➪ 3x = 15 - 2

➪ 3x = 13

★ $\large\pink{x = \sf{\dfrac{13}{3}}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ 5x = 52 + 8

➪ 5x = 60

➪ x = $\sf\dfrac{60}{5}$

★ $\large\pink{x = 12}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ 2x + 2 = 14

➪ 2x = 14 - 2

➪ 2x = 12

➪ x = $\sf\dfrac{12}{2}$

★ $\large\pink{x = 6}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ $\sf\dfrac{1}{4} \times x = 12 - 6$

➪ $\sf\dfrac{1}{4} \times x = 6$

➪ $\sf 1 \times x = 6 \times 4$

★ $\large\pink{x = 24}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ $\sf 2y = \dfrac{2}{5} - \dfrac{1}{5}$

➪ $\sf 2y = \dfrac{2-1}{5}$

➪ $\sf 2y = \dfrac{1}{5}$

➪ $\sf y = \dfrac{1}{5 \times 2}$

★ $\large\pink{y = \dfrac{1}{10}}$
