Question

resuelvo ecuaciones

a) 5 .(X+6) =75

b) 4 .X- 5.9 =54÷2


Necesito urgente Y que sea verificado por favor...Ayudaa

Answer 1

5 .(X+6) =75

5x+30=75

5x=75-30

5x=45

x=45/5

x=9



4 .X- 5.9 =54÷2

4x-45=27

4x=27+45

4x=72

x=72/4

x=18

Answer 2

5 .(X+6) =75
5x+30=75
5x = 75-30
5x = 45
x = 45/5
x = 9


4 .X- 5.9 =54÷2
4x - 45 = 27
4x = 27+45
4x = 72
x = 72/4
x = 18
