Answer:
x= -7
Step-by-step explanation:
Simplify both sides of the equation.
4(1−x)+2x=−3(x+1)
(4)(1)+(4)(−x)+2x=(−3)(x)+(−3)(1)(Distribute)
4+−4x+2x=−3x+−3
(−4x+2x)+(4)=−3x−3(Combine Like terms)
Add 3x to both sides.
−2x+4+3x=−3x−3+3x
x+4=−3
Subtract 4 from both sides.
x+4−4=−3−4
x=−7
The answer is B, C, and D. Like terms are terms with all the same variable, so 5x and -x are like terms.
C is correct. If we add -x to 5x, we get 4x. The other numbers remain unchanged because they have no like terms.
D is correct. Applying the rule of like terms, which is that like terms are numbers with the same variable, only add together numbers with the same variable.

Answer:
Step-by-step explanation:
The midpoint formula is:
where (x₁, y₁) and (x₂, y₂) are the points are the endpoints.
We are given the points: (2,4) and (6,8). Therefore,
Substitute the values into the formula.
Find the x coordinate first.
- Add 2 and 6: 2+6=8
- Divide by 2: 8/2=4
Find the y-coordinate next.
- Add 4 and 8: 4+8= 12
- Divide by 2: 12/2=6
The midpoint of EF is (4,6)
Answer:
the x terms
Step-by-step explanation:
there is a +x and a -x.
x-x=0,
x will cancel out
