Question

Select all the equations for which 7 is a solution. A.) x-5=12B.) 5+x=12C.) x+12=19D.) x-5=-12

Answer 1

a) 7 - 5 = 12

2 = 12 This is not a solution

b) 5 + 7 = 12

12 = 12 This is a solution

c) 7 + 12 = 19

19 = 19 This is a solution

d) x - 5 = -12

7 - 5 = -12

2 = -12 This is not a solution
