求以下等式中的 x 。不得使用计算器。

5x+4=5+9

-5+3(7-6) ² =2x

x-(2+4) ² =2x-(9-8)

4-1 ² +2(2+1) ² =x+2 ²

-2(4+6 ² )+x=100÷5 ²

5x+4=(5-3) ²

-1 ² +2÷(2+1) ² =x+2 ²

5+3(7-6) ² =2x

x-4 ² =2x-(3-1) ²

x-2+4 ² =2x-(3-1) ²

4-1 ² -3(2+6) ² =x+9

4-1 ² +3(2+6) ² =x+2 ²

x-(2+4) ² =2x

-2(4+6) ² +x=100÷5 ²

7-(3+2) ² =4-2x

-5-3(7-6) ² =2x

-3(4+6)+x=-40

x-2+4 ² =2x-(9-8)

(4-4) ² =2x-(3-1) ²

(7-3) ² +2=4-2x

(4-1) ² -3(2+6)=x-9

-2(4+6) ² +x=-100

(4-1) ² -3(2+6) ² =x-9

-2(4+6 ² )-x=100÷5 ²

(7-3) ² +3=-2(4-2x) C8v49O6AWl4mRetY8hXeUa494okqWplGTOcnr2sp67g3DUSg2I2d49hLsEmr3pmS
