This should be easy because we just have to use substitution method. Substitute the value of x from the second equation into the x of the first equation.
-4(2y) + 11y = 15
-8y + 11y = 15
3y = 15 ; y = 5
Substitute this value of y to either the first or second equation.
x = 2(5) = 10
The ordered pair is therefore (10,5).
Answer:
a:c=2.5:1.25
Step-by-step explanation:
2a:3b=5:6
2(2.5):3(2)=5:6
3(2):2(1.25)=6:2.5=36:15
