ANSWER: a=12 b=15
Explanation: (look at work below)
4a + 1b = 63 (eq1)
5a + 3b = 105 (eq2)
-12a + -3b = -189 (subt. eq1 from eq2)
————————-
-7a = -84
a = 12
4(12) + 1b = 63 (plug in the a value)
48 + 1b = 63
b = 15
Answer:
Step-by-step explanation:
0<5xb<5 divide all terms by 5
0<xb<1 divide all terms by x
0<b<x
If you meant 5b as in 5*b then:
0<5b<5 divide all terms by 5
0<b<1
b is infinitely many values between 0 and 1.
