Multiply the 1st row by 3
3x−12y=−3
3x+2y=39
Subtract the 2nd row from the 1st row.
−14y=−42
Solve for y (-14y=-42)
Divide both sides by −14.
Y= -42/-14
Two negatives make a positive.
Y=42/14
Simply 42/14 to 3
Y=3
Sub y=3 into both equations
3x-12x3=-3
X=11
Therefore,
X =11
Y=3
Answer:
1≤x
Step-by-step explanation:
3x+2(4x+2)≤2(6x+1)
3x+8x+4≤12x+2
4-2≤12x-3x-8x
2≤2x
1≤x
