INVERSE OPERATIONS: 51 = X - 12

63

Step-by-step explanation:

x - 12= 51

when you need to get rid of the 12 to get x by itself, you need to put it on the right hand side. to do this the operation is inverse of what it currently is, (-12)

move the -12 to  the right hand side, which inverses the operation to +12

so the equation is now:

x= 51+ 12

x= 63

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

x-3y=4
