Question

Me passem 10 equações pvr!

Answer 1

1) 5x = 10
x = 10/2
x = 5

2) 3 + x = 4
x = 4 - 3
x = 1

3) 10 - x = 5
10 - 5 = x
x = 5

4) 4x = 24
x = 24/4
x = 6

5) 12 - x = 6
12 - 6 = x
x = 6

6) 7x = 28
x = 28/7
x = 4

7) 10x = 10
x = 10/10
x = 1

8) 6x = 18
x = 18/6
x = 3

9) 4 + 2x = 6
2x = 6-4
2x = 2
x = 1

10) 20 - x = 17
x = 3
