Answer:
-9, -8
Step-by-step explanation:
x+(x+1)=7+3(x+1)
x+x+1=7+3(x+1)
2x+1=7+3(x+1)
2x+1=7+3x+3
2x+1=3x+10
2x+1-1=3x+10-1
2x-3x=3x-3x+9
-1x/-1=9/-1
x=-9/-8

Answer:
the numbers are 85 and -31.
Step-by-step explanation:
first, let the numbers be x and y.
so by question we have,
x+y=54.......(I)
x-y=116......(I I)
now, solve it through elimination method,
x+y=54
x-y=116
here, y and y cancelled out and we get,
or, x+x=54+116
or, 2x=170
or, x=170/2
therefore, x=85
now put value of x in any equation. let's put in eqn (I), we get,
or, x+y=54
or,85+y=54
or, y=54-85
so, y= -31
therefore, the numbers are 85 and - 31.
the sides could be 6 cm and 3 cm
the sides could also be 9 cm and 2 cm
the sides could also be 18 cm and 1 cm
