2x + y = -10
Step-by-step explanation:
Simplify −2(x+7)
y−4=−2x−14
Move all terms containing variables to the left side of the equation.
2x+y−4= −14
Move all terms not containing a variable to the right side of the equation.
2x + y = −10
Hope this helps
Answer 6 hours
Reason
7x + 9.50 = 55
-9.50. -9.50 subtract from both sides
_____________
