M10. If 3x + 7 = 16, what is the value of x?
a) 3
b) 4
c) 5
d) 6
ANSWER: a) 3
EXPLANATION:
To find the value of x in the equation 3x + 7 = 16, we can solve for x by performing algebraic operations. Here's the step-by-step solution:
3x + 7 = 16
Subtract 7 from both sides:
3x = 16 - 7
3x = 9
Divide both sides by 3:
x = 9 / 3
x = 3
Therefore, the value of x in the equation 3x + 7 = 16 is a) 3.
