(x )*2=1.5+37怎么解

(x-20)*2=1.5+37 2x-2*20=1.5+3.7 2x=1.5+3.7+40 2x=45.2 x=45.2/2 x=22.6

解: 16x-3=37 16x=37+3 16x=40 x=2.5

(3.5x–1.5x)–6=37 2x=37+6 2x=43 x=43/2 x=21.5 谢谢,请采纳

可以简算的啊 原式=1.5×61.4+1.5×37.6 =1.5×(61.4+37.6) =1.5×100 =150

(1)37×79?x=14, 13-x=14, 13-x+x=14+x, 13=14+x, 13?14=14+x?14, x=112;(2)1.5:315=x:423, 315x=1.5×423, 315x=7, 315x÷315=7÷315, x=2316.

x-1.5x=37.4 解:-0.5x=37.4 x=-74.8

答案:2/3

解(-5.2)-(-2.63)-1.5+(-3.8)-(-12.37) =(-5.2)+(2.63)-1.5-(3.8)+(12.37) =(-5.2)-(3.8)-1.5+(12.37)+(2.63) =-9-1.5+15 =6-1.5 =4.5

45✖️2.08十1.5✖️37.6 =15x3x2.08+15x3.76 =15x(6.24+3.76) =15x10 =150

你好: 原式=15.37x7.88+1.537x21.2 - 9.37x7.38-93.7x0.262 =15.37x7.88+15.37x2.12 - (9.37x7.38+9.37x2.62) =15.37x(7.88+2.12)- 9.37x(7.38+2.62) =15.37x10-9.37x10 =(15.37-9.37)x10 =6x10 =60
