Answer:
7=7 and 7=7
infinite solutions?
Explanation:
Let's solve for x.
3x+4y+7=3x+4y+7
Step 1: Add -3x to both sides.
3x+4y+7+−3x=3x+4y+7+−3x
4y+7=4y+7
Step 2: Add -4y to both sides.
4y+7+−4y=4y+7+−4y
7=7
Step 3: Add -7 to both sides.
7+−7=7+−7
0=0
Let's solve for y.
3x+4y+7=3x+4y+7
Step 1: Add -4y to both sides.
3x+4y+7+−4y=3x+4y+7+−4y
3x+7=3x+7
Step 2: Add -3x to both sides.
3x+7+−3x=3x+7+−3x
7=7
Step 3: Add -7 to both sides.
7+−7=7+−7
0=0
