I don’t know the answer to it

The answer is B, 3

Step-by-step explanation:

Because if the sum is 10 (x+y=10) and you have to subtract 4 to get the smaller number, 7-4=3 and 7+3=10

x= 7

y= 3

Step-by-step explanation:

First you have to make equations for it

x + y = 10

x - y= 4

Then you use just use the elimination method (Cross out the ys) to get to

2x = 14 which gets you x= 7. Then just substitute one on the equations 7 and solve to get y = 3.

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105
