2x-h=x+a (solve for x) (where exactly do i start and how do i solve for x? )

2x - h = x + a      add h to both sides

2x = x + a + h     subtract x from both sides

To solve for x, you have to get x by itself/alone on one side of the equation.

2x - h = x + a

First you can subtract x on both sides to get the x on one side. (you could subtract either 2x or x)

x - h = a

Next you add h on both sides to get x by itself.

x = a + h

and that is your answer

associative property hopes this ! : )

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
