write and equation...22 - 2x = 822 - 22 - 2x = 8 - 220 - 2x = -14-2x = -14-2x/-2 = -14/-2x = 7
2x+3 = 7 2x = 7-3 2x = 4 x = 2
Assuming the question is "solve for x", the answer is x=5
2x - 8 = 10 2x = 10 + 8 2x = 18 x = 18 / 2 x = 9

6x-8+2x-5 = 7-2x 6x+2x+2x = 7+8+5 10x = 20 x = 20/10 x = 2
you have to put either an equal sign or say that this equation "equals" something but if you are asking 8 - 2x = 7 well you move 8 to the other side so 8 -2x -8 = 7 - 8 -2x = -1 now you divide -2 on both sides x = 1/2
write and equation...22 - 2x = 822 - 22 - 2x = 8 - 220 - 2x = -14-2x = -14-2x/-2 = -14/-2x = 7
2x 5 -7 = 3
2x+3 = 7 2x = 7-3 2x = 4 x = 2
2x-1=7 1) add 1 to both sides: 2x=8 2) divide both sides by 2: x=4 4 is the answer
how do you solve 8+x=x+8

6x - 8 + 2x - 5 = 7 - 2x ?
2x+8 = 6 2x = 6-8 2x = -2 x = -1
