m = 11
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
12+(7+m)-(30)=0
m = 11
answer: [tex]m = 49[/tex]
work:
[tex]12 + (7+m )= 30[/tex] | distribute the plus into the parentheses
[tex]12 + 7 + m = 30[/tex] | add 12 and 7
[tex]19 + m = 30[/tex] | subtract 19 and move it over to 30
[tex]m = 49[/tex] | final answer
