Hope this helps! :)
Number 9 is B, and number 10 is D
2x + 7y + 3x + 5y
5x + 12y
Y = x + 5....so we sub in x + 5 for y in the other equation
4x + y = 20
4x + x + 5 = 20
5x + 5 = 20
5x = 20 - 5
5x = 15
x = 15/5
x = 3
y = x + 5
y = 3 + 5
y = 8
solution is (3,8)
Answer:
24
Step-by-step explanation:
5x - y ÷ 8
Let x=5 and y=8
5(5) -8÷8
PEMDAS
multiply and divide from left to right
25 -8÷8
25 -1
Then add and subtract
24
