Concept:A linear equation is solved by expanding brackets and then isolating the variable.Explanation:Given: 4(m+4)=−8.Expand the bracket by multiplying each term inside by 4:4×m+4×4=−84m+16=−8Subtract 16 from both sides:4m=−8−164m=−24Divide both sides by 4:m=4−24=−6Answer:m=−6, so the correct option is A.
