9x-5.2X6=4.8(
9x减5.2乘以6等于4.8这题该怎样解方程 -
解:9x减5.2乘以6等于4.8 9x-5.2*6=4.8 9x=4.8+5.2x6 9x=36 x=36÷9 x=4
解:9x-31.2=4.8 移项得9x=4.8+31.2 9x=36 x=36÷9 x=4
解:9x减5.2乘以6等于4.8 9x-5.2*6=4.8 9x=4.8+5.2x6 9x=36 x=36÷9 x=4
解:9x-31.2=4.8 移项得9x=4.8+31.2 9x=36 x=36÷9 x=4
9x=4.8+5.2x6 9x=36 x=4
这是一元一次方程,
5(x+1.5)=14.75 9x-5.2X6=4.8 2x+1.5x=4.2 18除以x=7.5 -
回答:18÷x=7.5 x=7.5X18 x=185
9x+5.2×6=4.8 9x+31.2=4.8 9x=-26.4 x=-44/15 9%x-4.5×0.2=1.8 0.09x-0.9=1.8 0.09x=2.7 x=30
9x-5.2x6=14.7 -
解题过程如下:9x-5.2×6=14.7 9x=14.7+5.2×6 9x=14.7+31.2 x=45.9÷9 x=5.1
9x=4.5X6 解:9x=27 x=27÷9 x=3
9x-(x-5)x6=54 -
详细步骤写在纸上了,
原方程可化为9x+480=840,移项得9x=840-480,合并同类项得9x=360。系数化为一,得x=40。方程的解为x=40
