Solve the system by the elimination method. Check your work. 2a + 3b = 6 5a + 2b - 4 = 0 Make sure there are NO SPACES in your answer. Include a comma in your answer. ANSWER: {( a0 )}
Question
Answer:
2a + 3b = 6.....multiply by 25a + 2b = 4 ...multiply by -3
----------------
4a + 6b = 12 (result of multiplying by 2)
-15a - 6b = -12 (result of multiplying by -3)
----------------add
- 11a = 0
a = 0
2a + 3b = 6
2(0) + 3b = 6
3b = 6
b = 6/3
b = 2
solution is (0,2) <===== :)
check...
2a + 3b = 6 5a + 2b = 4
2(0) + 3(2) = 6 5(0) + 2(2) = 4
6 = 6 (correct) 4 = 4 (correct)
solved
