Question

3) encuentra los valores desconocido
1) u+4=7
2) a+18=20
3)T-9=2
4)x+2=-4
5)y-6=-17
6)y+10+25=40
7)U+25-9=8

Answer 1

1) u = 3

2) a = 2

3) T = 11

4) x = -6

5) y = -11

6) y = 5

7) U = -8

Explicación paso a paso:

1) u+4 = 7

u = 7-4 = 3

2) a+18 = 20

a = 20-18 = 2

3) T-9 = 2

T = 2+9 = 11

4) x+2 = -4

x = -4-2 = -6

5) y-6 = -17

y = -17+6 = -11

6) y+10+25 = 40

y+35 = 40

y = 40-35 = 5

7) U+25-9 = 8

U+16 = 8

U = 8-16 = -8
