When 4 times the number x is added to 12, the result is 12+4x. Since this result is equal to 8, the equation 12 + 4x = 8 must be true.Subtracting 12 from each side of 12+4x=8 gives 4x=−4, and then dividing both sides of 4x=−4 by 4 gives x=−1. Therefore, 2 times x added to 7, or 7+2x, is equal to 7+2(−1)=5. Choice A is incorrect because −1 is the value of x, not the value of 7+2x.Choices C and D are incorrect and may result from calculation errors.
