Answer: y= -6.45 and y=5-x
Step-by-step explanation:
Subtract 5.1 from both sides.
-2y= 18-5.1
Simplify 18- 5.1 to 12.9
-2y=12.9
Divide both sides by -2
y= - 12.9/2
Simplify 12.9/2 to 6.45
y=-6.45
Factor out the common term 3.
3(x+y)=15
Divide both sides by 3.
x+y =15/3
Simplify 15/3 to 5.
x+y = 5
Sub. x from both sides
y= 5-x
