The answer is <span>y=-4x+12 because they just moved the 4x
</span>
2x-5=15
2x=20
x=10
the answer is B
Divide both sides by 49/36 to get y by itself:
Simplify this fraction:
Now you have your answer:
If, for example, you had x on one side and x on the other, then subtracting x from both sides "disappears" x. If no other power of x shows up on either side, then your equation either has no solution or is always true.
