3分之x加x等于36

x/3+x=36等式两边乘以3x+3x=36*34x=108x=27

x²+14x-48=0x²+14x+49=48+49(x+7)²=97x+7=±√97x1=√97-7,x2=-√97-7

54

x=0

x/5+x=48(1/5+1)x=48(6/5)x=48x=48÷6/5x=40

x^2+3x=12x^2+3x+9/4=12+9/4（x+3/2）^2=57/4x+3/2=1/2根号57x1=1/2根号57-3/2x2=-1/2根号57-3/2

13加x减12等于3

13+x-12=3===>x+1=3===>x=3-1===>x=2再问：看不懂阿

x/5+x=326x/5=32x=80/32x/5-x/4=243x/20=24x=16030%x=45x=4500/30=150X+12%X=2.241.12x=2.24x=2

1/4x+1/2x+12+12-x=x1/4x+2/4x-x+12+12=x24-1/4x=xx+1/4x=245/4x=24x=24÷5/4x=96/5

x/(10/7)=0.4x+127/10x=4/10x+127/10x-4/10x=123/10=12x=12*10/3x=40

2.5x12=3030+3x=363x=6,x=2..

12(2减3x)等于4x加4

X加3分之X等于12两边同时乘以33x+x=364x=36x=36÷4x=9很高兴为您解答,【the1900】团队为您答题.请点击下面的【选为满意回答】按钮,

0.48x+12=480.48x=36x=75再问：你这个是怎么算的，能详细点吗？再答：0.48x+12=480.48x=48-120.48x=36x=36÷0.48x=75

7x加5等于12求x

X的平方加12减7X=x²-7x+12=(x-3)(x-4)

X+X*2/7=36X*9/7=36X=36*7/9=28

X=15-27+36=24
