Answer:
4a + 5b - 6c = 2
in this equation we don't have any same families cuz three letters are different to one another. so we can do is
Let's solve for a.
4a+5b−6c=2
Step 1: Add -5b to both sides.
4a+5b−6c+−5b=2+−5b
4a−6c=−5b+2
Step 2: Add 6c to both sides.
4a−6c+6c=−5b+2+6c
4a=−5b+6c+2
Step 3: Divide both sides by 4.
4a/a = -5b +6c +2 / 4
a = -5/4 b + 3/2 c + 1/2
−3a−2b+7c=−15
Step 1: Add 2b to both sides.
−3a−2b+7c+2b=−15+2b
−3a+7c=2b−15
Step 2: Add -7c to both sides.
−3a+7c+−7c=2b−15+−7c
−3a=2b−7c−15
Step 3: Divide both sides by -3.
a = -2/3 b + 7/3 c + 5
-a+4b+2c = -3
−a+4b+2c=−3
Step 1: Add -4b to both sides.
−a+4b+2c+−4b=−3+−4b
−a+2c=−4b−3
Step 2: Add -2c to both sides.
−a+2c+−2c=−4b−3+−2c
−a=−4b−2c−3
Step 3: Divide both sides by -1.
a=4b+2c+3
