it should be 12 because when youmultiply you multiply everything by the same thing
Answer:
12
Step-by-step explanation:
First we solve for y
5y + 3x = 4
Pass the x to the other side of the equality and change signs since we moved it
5y = -3x + 4
We divide everything by 5 so we get a result for y
y = -3/5x + 4/5
in other words,
y = -0.6 + 0.8
Now we substitute
5(-0.6 + 0.8) + 3x = 4
5(0.2) + 3x = 4
1 + 3x = 4
3x = 4 - 1
3x = 3
x = 1
Now that we got the value for X & Y we do the equation for 15y + 9x
15(-0.6 + 0.8) + 9 (1)
15(0.2) + 9
3 + 9
Hope this helped
