Question

M 2.8 − 4.9 = −7.11

Answer 1

From this equation, we need to find the value of m

We first isolate the variable m with its coefficient from the other values, so:

m2.8 - 4.9 = -7.11

m2.8 = -7.11 + 4.9

A negative and a positive will make a negative,so:

m2.8 = -2.21

Next we isolate the variable m completely from the other value so we divide both sides by 2.8, so

m2.8 / 2.8 = -2.21 /2.28

m = -0.78

Therefore the value of m is  -0.78
