Answer:
4y = 3
Step-by-step explanation:
To subtract the 2nd equation from the first, negate all three of the second equation terms: 3x + 2y = -4
and then add (combine) this result to (with) the first equation:
-3x + 2y = 7
3x +2y = -4
----------------------
4y = 3 (this is the desired result))
Answer:
true
Step-by-step explanation:
given
= ( cross- multiply )
4x = 40 ( divide both sides by 4)
x = 10
Answer:
