What is the value of s in the equation 4(2s - 1) = 7s + 12?
Solution:
Given, the equation is 4(2s - 1) = 7s + 12
We have to find the value of s in the equation
By multiplicative property
4(2s - 1) = 8s - 4
So, 8s - 4 = 7s + 12
By grouping,
8s - 7s = 12 + 4
s = 16
Verification:
LHS: 4(2s - 1)
= 4(2(16) - 1)
= 4(32 - 1)
= 4(31)
= 124
RHS: 7s + 12
= 7(16) + 12
= 112 + 12
= 124
LHS = RHS
Therefore, the value of s is 16.
What is the value of s in the equation 4(2s − 1) = 7s + 12?
Summary:
The value of s in the equation 4(2s -1) = 7s + 12 is 16.
