Question

What is the answer to |4m-2|=10?

Answer 1

`\left \{ {{4m-2=10} \atop {4m-2=-10}} \right. \\ \left \{ {{4m=12} \atop {4m=-8}} \right. \\ \left \{ {{m= (12)/(4) } \atop {m=- (8)/(4) }} \right. \\ \left \{ {{m=3} \atop {m=-2}} \right.`

Answer 2

m = 3,-2, as

4m - 2 = 10 and 4m - 2 = -10

4m = 12 and 4m = -8

m = 3 and m = -2
