Dari 50 siswa di suatu kelas terdapat 37 siswa gemar Matematika, 29 siswa gemar Bahasa Inggris, dan 4 siswa tidak gemar Matematika maupun Bahasa Inggris. Banyak siswa yang gemar keduanya adalah ..

-x+10=5x-12 So first you need to put the x's on one side. You have to transfer 5x. So it will be -5x - x. When you transfer the 5, you change the sign. So if it was -3, it would be 3 when you move it. Now you move the 10. It has a plus infront of it so it will be negative. So now you have -5x -x=-10 -12. -10-12=-22. -5x-x=-6x. So you have -6x=-22. Now you have to rid of the 6. 6x is the same as 6 times x, so you use division. So you have x=22/6. (Since you have two negative numbers you can cross them out) and you can now simplify. Your answer would be... 3 2/3!

− x + 10 = 5 x − 12 6 x = 22 x = 6 22 ​ = 3 11 ​

To solve − x + 10 = 5 x − 12 , rearrange the equation, isolate the variable, and divide to find x = 3 11 ​ . Always check your solution by substituting it back into the original equation. Ensure the left and right sides are equal to validate your answer.
