Easy Question:
2x + 10 = 4x - 4
let all x's to the left and the rest to right
2x - 4x = -4 -10
-2x = -14
x = -14 / -2 = 7

2x+10=4x-4
Transpose 4x to the other side and 10 to the otherside
2x-4x=-4-10
-2x=-14
Divide -2 to both sides to get x
x=7
Check
2(7)+10=4(7)-4
14+10=28-10
24=24

4x + 6 - 2x + 6 = 2x + 12 = 2 ( x + 6 ) -4 - 5t + t - 10 = -14 -4t = - 2 ( 7 + 2t )

Q:2x+10=4x-4
A:Put numbers and Xs separately.
10+4=4x-2x
14=2x
2x and -4 are exchanging sides,so 2x has to be -2x while
-4 has to be 4.
So,x=7

2x + 10 = 4x - 4
10 + 4 = 4x - 2x
14 = 2x
14/2 = x
7 = x
Proof:
(2 * 7) + 10 = (4 * 7) - 4
14 + 10 = 28 - 4
24 = 24

First you add 4 to both sides. You are left with 2x+14=4x. Take away 2x from both sides and yu are left with 14=2x. Therefore x=7.

2x + 10 = 4x - 4
2x = 14
=> x = 7

move x-valus to one side, and numers to other.
2x+10=4x-4 / subtract 2x from both side
10=2x-4 /add 4 to both side
14=2x /divide both side with 2
7=x
check:2* 7+10=4*7-4
14+10-=28-4
24=24
