Answer:-
1.) 3x + 2 = 15
➪ 3x = 15 - 2
➪ 3x = 13
★ [tex]\large\pink{x = \sf{\dfrac{13}{3}}}[/tex]
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
2.) 5x - 8 = 52
➪ 5x = 52 + 8
➪ 5x = 60
➪ x = [tex]\sf\dfrac{60}{5}[/tex]
★ [tex]\large\pink{x = 12}[/tex]
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
3.) 2(x+1) = 14
➪ 2x + 2 = 14
➪ 2x = 14 - 2
➪ 2x = 12
➪ x = [tex]\sf\dfrac{12}{2}[/tex]
★ [tex]\large\pink{x = 6}[/tex]
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
4.) 1/4 x + 6 = 12
➪ [tex]\sf\dfrac{1}{4} \times x = 12 - 6[/tex]
➪ [tex]\sf\dfrac{1}{4} \times x = 6[/tex]
➪ [tex]\sf 1 \times x = 6 \times 4[/tex]
★ [tex]\large\pink{x = 24}[/tex]
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
5.) 1/5 + 2y = 2/5
➪ [tex]\sf 2y = \dfrac{2}{5} - \dfrac{1}{5}[/tex]
➪ [tex]\sf 2y = \dfrac{2-1}{5}[/tex]
➪ [tex]\sf 2y = \dfrac{1}{5}[/tex]
➪ [tex]\sf y = \dfrac{1}{5 \times 2}[/tex]
★ [tex]\large\pink{y = \dfrac{1}{10}}[/tex]
