Answer:
x = 6 and the +4x is wrong
Step-by-step explanation:
2x + 4x + 4 = 4(x + 4)
6x + 4 = 4x + 16
+4x +4x <--( <u>This part is wrong</u> )
10x + 4 = 16
-4 -4
10x = 12
10 10
x = 1.2
Correct steps
2x + 4x + 4 = 4(x + 4)
6x + 4 = 4x + 16
-4x -4x
2x + 4 = 16
-4 -4
2x = 12
2 2
x = 6

Hope this helps. Have a great day!
The sum of any two rational numbers is rational. Both of these numbers are rational, therefore adding them will give us another rational number.
Answer:
y= mx+c
-4= -3/5(-5) + c
-4= -3/5 *-5+ c
-4=3+c
-4-3=c
-7=c
therefore the equation of the line is y=-3/5x-7
Step-by-step explanation:
the equation of a line is
y=mx +c
where y is the y coordinate
where m is the slope
where x is the x coordinate
where c is the y- intercept
