7.8×5+5x=65.5

7.8×5+5x=65.5 39+5x=65.5 5x=65.5-39 5x=26.5 x=5.3

5·5x+6·7=7·8 25x+42=56 25x=14 x=14/25 如果不懂,请追问,祝学习愉快!

8/5x7/6+7/1×8/5用简便方法计算 8/5x7/6+7/1×8/5 =5/8*(6/7+1/7) =5/8*1 =5/8

7x+5=8+5x 7x-5x=8-5 2x=3 x=3/2 x=1.5

5.5x=1.1 解得 x=0.2

X+7/8X=2/5 15/8x=2/5 x=2/5÷15/8 x=16/75

6x+5=5x+8 6X-5X=8-5 X=3

3/5+2/5x=7/8 解:2/5x=7/8-3/5 2/5x=35/40-24/40 2/5x=11/40 x=11/40*5/2 x=11/16

70-5+5x=120 65+5x=120 5x=120-65 5x=55 x=55/5 x=11

7分之5X÷14分之5=8分之7 5X/7÷5/14=7/8 5X/7×14/5=7/8 2X=7/8 X=7/8÷2=7/8×1/2 X=7/16
