Question

Solve. 4x+5y=40 3x=15

Answer 1

First, let's solve the second equation for x:
3x = 15
Divide both sides by 3:
x = 5

Now we can substitute this value of x into the first equation:
4(5) + 5y = 40
20 + 5y = 40
Subtract 20 from both sides:
5y = 20

Now divide both sides by 5:
y = 4

So the solutions to the system of equations are x = 5 and y = 4.
