Answer:
−20x − 8
Step-by-step explanation:
Answer:
x = 2, y = 1
Step-by-step explanation:
x + 4y = 6 and y = 3 - x have to be rearranged: x + 4y = 6 and x + y = 3
You subtract the equations to eliminate one of the variables (x) so that the other can be found
25% is 1/4 so you do 8 times 1/4 and that's 2.
