10x ÷ 5 = 30
Step 1: To isolate 10x multiply 5 to both sides. Multiplication is the opposite of division and will cancel 5 on the left side and bring it over to the left
10x ÷ ( 5 × 5) = 30 × 5
10x ÷ 1 = 150
10x = 150
Step 2: To isolate x divide 10 to both sides. This will cancel 10 from the left side and bring it over to the right
10x/10 = 150/10
x = 15
Check:
10 (15) ÷ 5 = 30
150 ÷ 5 = 30
30 = 30 --------------------------------------------------> Correct!
x = 15
Hope this helped!
