Question

3(82+x)=471 (x-1.8)÷4=2.5 5((X-1.8)=1.7 6(1.5+x)=13.8

Answer 1

3(82+x)=471 (x-1.8)÷4=2.5 5(X-1.8)=1.7

3*82+3x=471 (x-1.8)÷4*4=2.5*4 5(X-1.8)/5=1.7/5

246+3x=471 x-1.8=10 X-1.8=0.34

246+3x-246=471-246 x-1.8+1.8=10+1.8 X-1.8+1.8=0.34+1.8

3x=225 x=11.8 x=2.14

3x/3=225/3

x=75

6(1.5+x)=13.8

6*1.5+6x=13.8

9+6x=13.8

9+6x-9=13.8-9

6x=4.8

6x/6=4.8/6

x=0.8
