37x - 23x - 8x = 72 x 56x + 31x - 79x = 64

Question

37x - 23x - 8x = 72 x

56x + 31x - 79x = 64

Answer 1

37х-23х-8х=72

6х=72

х=72:6

х=12

 

56х+31х-79х=64

8х=64

х=64:8

х=8

Answer 2

37х-23х-8х=72

(37-23-8)х=72

6х=72

х=72/6

х=12

 

 

56х+31х-79х=64

(56+31-79)х=64

8х=64

х=64/8

х=8
