Answer:
11- y= -x - 7
12- y= 3x + 17
14= y= -4x+5
15= y= -3/5x + 3
Step-by-step explanation:
11- y+x=-7
move the variable to the right-hand side and change its sign
y=-7-x
use the commutative property to reorder terms
y=-x-7
12- y- 3x = 17
Move variable to the right-hand side and change its sign
y=17+3x
reorder terms
y=3x+17
14. -2y= 8x-10
change signs on both sides
2y=-8x+10
divide both sides by 2 to get Y isolated
y= -4x+5
15. 3x + 5y = 17
move the variable to the right-hand side and change the sign
5y=15-3x
to isolate the y, we need to divide each side by 5
y= 3- 3/5x
now we re-order the terms
y= -3/5x + 3
