Answer:

Step-by-step explanation:
Eqn. 1 ----> 4y = x
Eqn. 2 ----> 5x-10y = -50
(Simplifying eqn.2 further)


(Substituting the value of x from eqn. 1)



Now, substituting the value of y in eqn. 1 ,

One factor that affects the slope of the aggregate demand curve is the multiplier effect is a "true" statement.
<h3>What is
aggregate demand curve?</h3>
Aggregate demand would be a macroeconomic term which refers to the total consumption of goods and services in a given period at any price level.
Some key features regarding the aggregate demand curve?
- Since the two metrics are estimated in the same way, aggregate demand over time corresponds gross domestic product (GDP).
- GDP is the total quantity of products and services created by an economy, whereas aggregate demand is indeed the desire or demand for those goods.
- The aggregate demand as well as GDP rise or fall together as a result of using the same calculation methods.
- All consumer goods, capital equipment (factories & equipment), export markets, imports, & government spending programs are included in aggregate demand.
- As long as the variables trade for the same market value, they are all considered equal.
