6x+4y=34
A.6
B.2
C.-2
D.-4
For this case we have the following system equations:
To use the elimination method we must multiply the first by -2. So:
In this way, if we add the equations, the variable y is eliminated.
Answer:
-2

Answer:
He above is correct 18 is the answer
Step-by-step explanation:
you divide 90 by 3 and you get 30 then you multiplie that by 4 120 then multiplie by 3
Plz Tell me if im wrong
the possible factors are (b-2) and (3a+4) but out of the possible following choice tho the answer would be (3a+4)
The expression 2a - 4 is a factor of 3ab - 6a + 4b - 8.
The expression 2a - 4 is a factor of 3ab - 6a + 4b - 8.
To check if an expression is a factor, we can substitute the values of a and b into the expression and see if it simplifies to zero. When we substitute a = 1 and b = 2 into 2a - 4, we get 2(1) - 4 = 2 - 4 = -2. And when we substitute these values into 3ab - 6a + 4b - 8, we get 3(1)(2) - 6(1) + 4(2) - 8 = 6 - 6 + 8 - 8 = 0. Since the expression evaluates to zero, it is a factor of the given expression.
