Answer: 3x=-7
Step-by-step explanation:
step1: move the constant to the right by adding its opposite on both sides
3x=0-7
Step2: simplify: 3x=-7
Answer:
A. (5,2)
Step-by-step explanation:
If you go to solve the equation you would first try to get y by itself in the first equation and you would do that by subtracting x on both sides. Then you would have y=7-x and then you would plug the second equation in for the x and get the equation y=7-y-3 because you distribute the negative sign of the x to both the y and 3. Then you combine like terms and get y=4-y and then add the y to both sides and get 2y=4 and then divide both sides by 2 and get y=2. Then you plug in y in the first equation and get x+2=7. Then you subtract 2 from both sides and get x=5.
