Question

Find the sum $(w-7)+(-6w-5)$

Answer 1

Hint: Simplify by collecting like terms.

Step 1: For simplifying let’s rewrite the expression

$(w-7)+(-6w-5)$

Remove the unnecessary parentheses,

$w-7+(-6w-5)$

Step 2: Now, When there is a + in front of an expression in parentheses, the expression remains the same.

So our expression will reduce to: $w-7-6w-5$

Collect like terms,

$w-6w-7-5$

Remember if a term doesn’t have a coefficient, it is considered as 1.

Now simplify the terms, $-5w-12$

Hence the sum is $-5w-12$
