What is the value of x in the equation 2 point 5 times open paren 6 x minus 4 close paren is equal to 10 plus 4 times open paren 1 point 5 plus 0 point 5 x close paren ?
Answer
A
13
B
13
C
2
D
12
Explanation
Distribute on both sides: 2.5(6x − 4) = 15x − 10, and 10 + 4(1.5 + 0.5x) = 16 + 2x. Then 15x − 10 = 16 + 2x, so 13x = 26 and x = 2. The correct choice is C, 2.
