What is the value of s in the equation 4(2s − 1) = 7s + 12? (4 points) A.12
B.16
C.32
D.34

B. 16

Step-by-step explanation:

Solve for s:

4(2s - 1) = 7s + 12

Expand out terms of the left hand side:

8s - 4 = 7s + 12

Subtract 7 s from both sides:

(8s - 7s) - 4 = (7s - 7s) + 12

8s - 7s = s:

s - 4 = (7s - 7s) + 12

7s - 7s = 0:

s - 4 = 12

Add 4 to both sides:

s + (4 - 4) = 4 + 12

4 - 4 = 0:

s = 12 + 4

12 + 4 = 16:

s = 16

its 4 because 2 times 2 is 4, if you double the number two you get four

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
