Answer:
let the two number is x and y
x + y = 4 1/2 .....(i)
x - y = 3 1/4 ......(ii)
adding question (i) and (ii)
x + y = 9/2
x - y = 31/4
=> 2x = 31/4
x = 8/31
substituting the value x in equation 1
8/31 + y = 9/ 2
y = 9/2 - 8/31
y =203/62
the value of x = 8/31
y = 203/62
Answer:
B
Step-by-step explanation:
Take the second equation for example, just solve like there is an equal sign.
13x+25< -1
13x<-26
X '='-2
X<-2
Looks to me like y= x + 1
