Answer:
x = 1/2 y = -1/3
Step-by-step explanation:
Split it into 2 equations:
10x-9y=8
and
21y+15x=0.5
10x - 9y = 8
Step 1: Divide both sides by 10:
x = (8+9y)/(10)
Substitute x = (8+9y)/(10) into 21y+15x=0.5 :
21y + (3(8+9))/(2) = 0.5
Solve for y
<u>y= -1/3</u>
Substitute y= -1/3 into x = (8+9y)/(10)
<u>x = 1/2</u>

A should be the right answer because 4*5/4=5 + 5*2=10 and 5+10=15.
Y = 6x - 4
basically, we just sub answer choices in to see which ones make the equation true.
answer is : (0,-4) , (1,2) , (3,14)
Determine the slope and y-intercept from the following equation: 4x + y = -10
Question 9 options:
