A number raised to a power is the same as multiplying the number by itself the number of times of the power.
11^2 = 11 x 11 = 121
The answer is 121
Answer:
(5,7)
Step-by-step explanation:
Substitute 2x-3 for y in the 2nd equation, obtaining: x + 2x - 3 = 12. Then 3x = 15, and x = 5. Subbing 5 for x in the 1st equation results in: y = 2(5) - 3 = 7. The solution is therefore (5,7).
