What is the answer to x+4=6
sattari [20]

Answer:

x=2

Step-by-step explanation:

When solving an algebraic equation, you have to get x alone

you do this by doing the inverse of whatever is efecting x

in this case it is x+4 so you subtract 4 from x+4

x+4-4=x

but when doing something like this, you have to do the same thing to both sides

x+4<em><u>-4</u></em>=6<u><em>-4</em></u>

x=2

please mark me brainliest!

The equation's X-y= 2, -2y=-2, X+ y = 2, and x+2y=-2 are shown on the graph below.
ziro4ka [17]

Answer:

A.) x-y=2 and x+2y=-2

Step-by-step explanation:

For option A, we have:

x-y=2

x+2y=-2

Subtract the first equation from the second, to get:

2y--y=-2-2

This implies that:

2y+y=-2-2

Simplify to get:

3y=-4

Divide both sides by 3 to get:

y =  -  \frac{4}{3}  =  - 1.3

We substitute y=-1.3 into the first equation to get:

x--1.3=2

x+1.3=2

x=2-1.3

x=0.7

The solution is (0.7,-1.3), which is approximately (0.7, -1.4)

By inspection, all the other factors have solutions not close to (0.7, -1.4)
