The unknown number is 24
Answer:
y = <u>x</u> + 2
2
i think this is helpful
Step-by-step explanation:
equation= <u>y</u><u> </u><u>-</u><u> </u><u>1</u><u> </u><u> </u> = <u>1</u>
x - -6 2
then you close multiplication
= 2(y -1)= 1(x - -6)
2y - 2 = x - -6
you make Y as a subject
2y = x- -6 + 2
2y = x + 4
then you divide by 2 on both sides
<u>2</u><u>y</u> = <u>x</u> + <u>4</u>
2 2 2
y = <u>x</u> + 2
2
Answer:
x = 2 and y = -2
Step-by-step explanation:
We must first eliminate the y-variable:
2x + 3y = -2
3x - 6y = 18
4x + 6y = -4
3x - 6y = 18
_________
7x = 14
x = 2
Since we know x=2, we plug that back into one of the original equations to find y:
2x + 3y = -2
2(2) + 3y = -2
4 + 3y = -2
3y = -6
y = -2
Therefore, x = 2 and y = -2
