4(2s − 1) = 7s + 12
Multiply the bracket by 4
(2s)(4)(-1)(4)= 7s+12
8s-4= 7s+12
Move 7s to the other side. Sign changes from +7s to -7s.
8s-7s-4= 7s-7s+12
8s-7s-4= 12
Move -4 to the other side. Sign changes from -4 to 4.
8s-7s-4+4= 12+4
8s-7s= 16
s= 16
Answer: s= 16
Answer: [tex]s=16[/tex]
Step-by-step explanation:
Given the following equation:
[tex]4(2s-1) = 7s + 12[/tex]
You need to solve for "s" in order to find its value:
- Apply Distributive Property:
[tex]8s-4 = 7s + 12[/tex]
- Add 4 to both sides of the equation:
[tex]8s-4+4 = 7s + 12+4\\\\8s=7s+16[/tex]
- Finally, subtract [tex]7s[/tex] to both sides of the equation:
[tex]8s-7s=7s+16-7s\\\\\\\\s=16[/tex]
