Answer:
[tex] \huge{ \boxed{ \tt{a = 5}}}[/tex]
Step-by-step explanation:
[tex] \text{3a + 2(2a - 1) = 33}[/tex]
Distribute 2 through the parentheses
↦[tex] \text{3a + 4a - 2 = 33}[/tex]
Add the terms : 3a and 4a
↦ [tex] \text{7a - 2 = 33}[/tex]
Move 2 to right hand side and change it's sign
↦ [tex] \text{7a = 33 + 2}[/tex]
Add the numbers : 33 and 2
↦ [tex] \text{7a = 35}[/tex]
Divide both sides by 7
↦[tex] \text{7a\: / \: 7 \: = 35 \: / \: 7}[/tex]
↦ [tex] \text{a = 5}[/tex]
Hope I helped!
