Question

If ( x+1, y-1 ) = (6, 7). The value of x and y are:​

Answer 1

please give me

Explanation:

$(x + 1) (y - 1) = (6)(7) \\ x + 1 = 6 \\ x = 6 - 1 \\ = 5 \\ x = 5 \\ (y - 1) = 7 \\ y - 1 = 7 \\ y = 7 + 1 \\ = 8 \\ y = 8$

Answer 2

Answer:

(x+1,y-1)=(6,7)

Since the ordered pair are equal, corresponding elements are equal. hence, x+1=6 ...(1) and y-1=7 ...(2)

Solving 1

x+1 =6

x=6-1

x=5

Solving 2

y-1=7

y=7+1

y=8

x=5, y=8
