Answer: x = -10/7
1. Simplify 2 • 2 to 4
4 + 7x + 6 = 0
2. Simplify 4 + 7x + 6 to 7x + 10.
7x + 10 = 0
3. Subtract 10 from both sides.
7x = -10
4. Divide both sides by 7.
X = -10/7
Answer:
x=10, y = -20
Step-by-step explanation:
y = –5x + 30

y = -50 +30
y = -20
x=10, y = -20
The answer is 4 if I am correct
