PLZZZ CHECK THIS QUICKLY!!
ik i shouldn't put a time limit and im srry but this is really urgent i didn't know how late it was DX PLZZ HELP!
plz answer some one
PLZ I CANT AFFORD TO GET ANY WRONG!
ok i'll do it by myself once again
<<ok i'll do it by myself once again>>
Good idea.
Using all caps, !!!!!!!!!, and calling everything URGENT is a good way to be ignored.
How can there be a D answer when there are only three choices?
Try combining terms. You will be led to either a linear equation (with one solution) or the variable will drop out, leaving nonsense such as
-6 = 0
which has no solution.
To check the answers, let's go through each equation and solve for the variable.
1. 2(x - 3) = 2x
First, distribute the 2 on the left-hand side: 2x - 6 = 2x
Now, subtract 2x from both sides: -6 = 0
Since this equation results in -6 = 0, which is false, there are no solutions. Therefore, the correct answer is "no solutions." (B)
2. 3(y - 3) = 2y - 9 + y
First, distribute the 3 on the left-hand side: 3y - 9 = 2y - 9 + y
Combine like terms: 3y - 9 = 3y - 9
Subtract 3y from both sides: -9 = -9
Since this equation results in -9 = -9, which is true, there are infinitely many solutions. Therefore, the correct answer is "infinitely many solutions." (C)
3. 10x - 2 - 6x = 3x - 2 + x
Combine like terms: 4x - 2 = 4x - 2
Now, subtract 4x from both sides: -2 = -2
Since this equation results in -2 = -2, which is true, there are infinitely many solutions. Therefore, the correct answer is "infinitely many solutions." (C)
4. 4(x + 3) + 2x = x - 8
First, distribute the 4 on the left-hand side: 4x + 12 + 2x = x - 8
Combine like terms: 6x + 12 = x - 8
Subtract x from both sides: 5x + 12 = -8
Subtract 12 from both sides: 5x = -20
Divide both sides by 5: x = -4
Since the equation has a specific value for x (-4), it has one solution. Therefore, the correct answer is "one solution." (A)
Based on the explanations provided, the correct answers are:
1) B (no solutions)
2) C (infinitely many solutions)
3) C (infinitely many solutions)
4) A (one solution)
