4 (54X4 +129 - (80/8-4)=​

Answer 1

Explicação passo-a-passo:

1 (89-40+70) + (129-49 +87)=

              (119)+ (167)=

                   286

2 ( 127-39 +42) + (420-189 +42) =

                (130)+(273)=

                    403

3 (48×3 - 100) + (32/4 +10 )

                (44)+(18)=

                     62

4 (54X4 +129) - (80/8-4)=​

              (345)-(6)=

                 339

Answer 2

1- (89-40+70)+(129-49+87)
119+167= 286
2- (127-39+42)+(420-189+42)
130+273= 403
3- (48x3-10) + (32/4 +10)
134+18= 152
4- (54x4+129) - (80/8-4)
345-6= 339
