m + (-9.5) = -7.8
First, simplify your brackets. / Your problem should look like: \(m + -9.5 = -7.8\)
Second, change addition to subtraction. / Your problem should look like: \(m - 9.5 = -7.8\)
Third, add 9.5 to both sides. / Your problem should look like: \(m = -7.8 + 9.5\)
Fourth, simplify. / Your problem should look like: \(m = 1.7\)
Answer: m = 1.7
