To solve for k, we will start by simplifying the equation.
The given equation is: 13 = -4(k + 10) - 7
Perform the distributive property to eliminate the parentheses:
13 = -4k - 40 - 7
Combine like terms:
13 = -4k - 47
Add 47 to both sides of the equation:
13 + 47 = -4k - 47 + 47
60 = -4k
Finally, divide both sides of the equation by -4 to solve for k:
60/(-4) = k
k = -15
Solve for k.
13 = –4(k + 10) + –7
