Answer:

Step-by-step explanation:

Let the first number be = X

Let the second number be= y

X+Y=86 -------1

X-Y=38 --------2

adding equation 1 & 2

2X=124

X= 62

Put X in equation 1

62+Y= 86

Y=86-62

Y= 24

Therefore X= 62 and y=24

MrMuchimi
7(3r-1)-(r+5)=-52

21r-7-r-5=-52

21r-r-5-7=-52

20r-12=-52

Add 12 to both sides

20r=-40

Divide by 20

r=-2
