Question

1.) 7x+8=29
2.) 6x+6=36
3.) 7+6x=19
how do you solve these problems?

Answer 1

1.) x= 3

2.) x=5

3.) x=2

Explanation:

1) 7x+8=29

( -8). 7x=21. (-8)

(÷7). x=3. (÷7)

2). 6x+6=36

6x=30. subtract 6

x=5. divide by 6

3). 7+6x=19

6x+7=19. rearrange it

6x=12. subtract 7

x=2. divide by 6

Answer 2

`\huge\mathbb\red{ANSWER}`

`\mathsf \purple{7x + 8 = 29}`

`\mathsf \pink{7x + 8 - 8 = 29 - 8}`

`\mathsf \purple{7x = 21}`

`\mathsf \pink{ (7x)/(7) = (21)/(7) }`

`\mathsf \purple{x = 3}`

`\mathsf \red{6x + 6 = 36}`

`\mathsf \green{6x + 6 - 6 = 36 - 6}`

`\mathsf \red{6x = 30}`

`\mathsf \green{ (6x)/(6) = (30)/(6) }`

`\mathsf \red{x = 5}`

`\mathsf \blue{7 + 6x = 19}`

`\mathsf \orange{ - 7 + 7 + 6x = 19 - 7}`

`\mathsf \blue{6x = 12}`

`\mathsf \orange{ (6x)/(6) = (12)/(6) }`

`\mathsf \blue{x = 2}`
