To solve for two unknown variables (a and b) you need 2 independent equations. You have only one.
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
2a-4b = -2
2a + 4b - 52a + 4b - 52a + 4b - 52a + 4b - 5
2a-3+4b-2a-b-3+5=3b-1
2a-3+4b-2a-b-2a-b-3+5 Can be simplified to: 3b-1
2a + 4b
1a+3b 2a+4b=3a +7b
Do this: write it out 2 |2a + 4b + 8 Now what divides into all the numbers? ---------------- a + 2b + 4 answer is 2(a+2b+4)
36 -20 = 16
4b - 1 = -4 + 4b + 3first, simplify and add together what you can.4b - 1 = -1 + 4b4b = 4bbecause 4b is always equal to 4b, the answer is infinite.
2a(3a - 4b + 1)
2a*4b*(-3c) = ? 2 * 4 * -3 * a * b * c = ? -24abc
