Answer: D
Step-by-step explanation:
Answer:
(2, 0)
Step-by-step explanation:
Given the simultaneous equation
2x-y = 4
3x+y = 6
Add both equation
2x+3x = 4 + 6
5x = 10
x = 10/5
x = 2
Substitute x = 2 into equation 1
From1 ;
2x-y = 4
2(2) - y = 4
4 - y = 4
y = 4-4
y = 0
Hence the solution to the system of equation is (2, 0)
Which TWO expressions are equivalent to<em> </em><em>(x - y) </em>2/3 - 3/4 <em>(y-x)</em>
If it is a mixed number than a real world problem would be:
Kim was baking cookies. She needed 1 1/2 cups of flour for one batch. If she wanted to bake 2 batches she would need 15 cups. What operation dd I do to get from 1 1/2 to 15 cups?
