Question

If 3w +6=21 find the value of w

Answer 1

`3w + 6 = 21 \\ 3w = 15 \\ w = 5`

Answer 2

Hey there!

`\mathsf{3w + 6 = 21}`

SUBTRACT 6 to BOTH SIDES

`\mathsf{3w + 6 - 6 = 21 - 6}`

CANCEL out: 6 - 6 because that gives you 0

KEEP: 21 - 6 because it helps you solve for w

`\mathsf{21 - 6 = \boxed{\bf 15}}`

NEW EQUATION:
`\mathsf{3w = 15}`

DIVIDE 3 to BOTH SIDES

`\mathsf{(3w)/(3)=(15)/(3)}`

CANCEL out:
`\mathsf{(3)/(3)}` because that gives you 1

KEEP:
`\mathsf{(15)/(3)}` because that gives you the value of w

NEW EQUATION:
`\mathsf{(15)/(3)=w}`

`\mathsf{(15)/(3)=\boxed{\bf 5}}`

`\boxed{\boxed{\large\textsf{Therefore, your answer: \huge \bf w = 5}}}\huge\checkmark`
