Question

2×3x+8u÷(-2/4)= -66

What is x and u
A. 5 and 6
B. 2 and 5
C. 6 and 5
D. 8 and 9
E. 4 and 3

Answer 1

The appropriate choice is
A. 5 and 6


The equation can be rewritten as
6x -16u = -66
or
3x -8u = -33

___
The graph shows where the various answer options lie in relation to the line described by the equation. Only (5, 6) lies on the line, so that is the only appropriate set of values for (x, u).
