Answer:
Step-by-step explanation:
When multiplying fractions, you multiply the numerators together and denominators together. This means that the problem above can be rewritten as, . Then, multiply this out to get
. However, this fraction can be simplified by dividing the numerator and denominator by 2. This gives the final answer,
.
Answer:
Choice D
Step-by-step explanation:
Several techniques do exist for solving systems of linear equations; substitution method, graphical method and elimination method. For this scenario, since we are not restricted on the method, I opted to use the graphical technique.
The graphical solution to a system of linear equations is the point where the lines intersect. If the lines are never intersect then the system has no solution.
The attachment below shows that the system intersects at the point (-3, 26). Therefore, the system has a single solution: x = -3, y = 26.
