Х+120=45*6 у*20=450+120+130

Question

Х+120=45*6 у*20=450+120+130

Answer 1

45+120=165*6=990, 450*20=9000+120=9120+130=9250

Answer 2

1) X + 120 = 45 × 6
X + 120 = 270
X = 270 - 120
X =150
______________
150 + 120 = 45 × 6
270 = 270

2) y × 20 = 450 + 120 + 130
у × 20 = 700
у = 700 : 20
у = 35
_____________________
35 × 20 = 450 + 120 + 130
700 = 700
