Answer 1

`\text {Hey! Let's Solve this Equation!}`

`\text {\underline {The First Step is to Subtract 2x}}`

`\text {2x+30-5x=5x+9-5x}`

`\text {Your New Problem Is: -3x+30=9}`

`\text {\underline {The Next Step is to Subtract 30}}`

`\text {3x+30-30=9-30}`

`\text {Your New Problem Is: -3x=-21}`

`\text {\underline {The Final Step is to Divide -3}}`

`\text {-3x/-3=-21/-3}`

`\text {Your Answer Would Be:}`

`\fbox {x=7}`

`\text {Best of Luck!}`

Answer 2

7

Explanation:

get the x on the same side.

subtract 2x from both sides

30=3x+9

then get the variables on one side by themselves. subtract 9 from both sides.

21=3x

now divide by 3 on both sides.

there's your answer.
