Answer 2

Hello castilloesperanza399!

`\huge \boxed{\mathbb{QUESTION} \downarrow}`

Evaluate the expression when a= -7 and b=2

a-4b.

`\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}`

It's given that,

• a = -7
• b = 2

Our expression is 'a - 4b'. We already have the values of a & b, so to solve it we need to substitute the values given in the place of a & b.

`a - 4b \\ = ( - 7) - 4(2) \\ = - 7 - 8 \\ = \large\boxed{\boxed{ \bf- 15}}`

• The value of the expression will be -15.
