Question

Me ayudan porfis

5/4-x= 2/3

5/2+1/5=2/3-x

x+1/2=3/4

3/7+x= 5/7+1/1

2/3+1/5= x+1/2

Answer 1

5/4 -x = 2/3
1'25 -x = 0'66
-x = 0'66 - 1'25
-x = -0'59
x = -0'59/-1 = 0'59

5/2 +1/5 = 2/3 -x
2'5 + 0'2 = 0'66 -x
2'5 + 0'2 -0'66 = -x
1'79 = -x
1'79/-1 = x
-1'79 = x

x + 1/2 = 3/4
x + 0'5 = 0'75
x = -0'5 + 0'75
x = 0'25

3/7 +x = 5/7 + 1/1
0'429 + x = 0'714 + 1
x = 0'714 + 1 -0'429
x = 1'285

2/3 + 1/5 = x + 1/2
0'66 + 0'2 = x + 0'5
0'66 + 0'2 -0'5 = x
0'36 = x
