Y=5-3x
5x-4y=-3
y=5-3x
-4y=-3-5x
----------------
-3y=2-7x
-3(y)=2-7(x)
u can try plugging in any number for y
-3(3)=2-7x
9=2-7x
-2 -2
7=7x
-- --
7 7
1=x
so 3,1
Answer:
That is not possible
Step-by-step explanation:
Answer:
y = 10
Step-by-step explanation:
substitute x = - 3 into the equation
(4 × - 3) + 2y = 8
- 12 + 2y = 8 ( add 12 to both sides )
2y = 20 ( divide both sides by 2 )
y = 10
The logarithm that is expanded correctly is ㏒₉ 7/(ab)² = log₉ 7 - 2log₉ b - 2log₉ b. It follows the law of logarithm for a fraction, log (a/b) = log a - log b, for a monomial, log ab = log a + log b and for a variable with exponent, log a² = 2log a. The answer is therefore letter C. The rest of the answers are not properly expanded.
