Question

What values of b satisfy 4(3b + 2)2 = 64?

Answer 1

=) 12b + 8 + 2 = 64

=) 12b + 10 = 64

=) 12b = 64 - 10

=) b = 54/12

=) b = 9/2

=) b = 4.5

`\\ \\`

`\dashrightarrow \tt4(3b + 2)2 = 64`

`\\ \\`

`\dashrightarrow \tt4 * 2(3b + 2) = 64`

`\\ \\`

`\dashrightarrow \tt8(3b + 2) = 64`

`\\ \\`

`\dashrightarrow \tt(3b + 2) = (64)/(8)`

`\\ \\`

`\dashrightarrow \tt(3b + 2) = \cancel (64)/(8)`

`\\ \\`

`\dashrightarrow \tt3b + 2=8`

`\\ \\`

`\dashrightarrow \tt3b=8 - 2`

`\\ \\`

`\dashrightarrow \tt3b=6`

`\\ \\`

`\dashrightarrow \tt{}b= (6)/(3)`

`\\ \\`

`\dashrightarrow \tt{}b= \bf2`
