Answer:
450 = 50x
Step-by-step explanation:
50x = 450
x = 450 / 50
x = 9
Answer:
-9
Step-by-step explanation:
-1y+11=20
-11= -11
-1y=20-11
-1y=9
-9
Steps:
1. Substitute the y in 4x + 10 with -5x-10
-5x-10= 4x + 10
2. Add 5x on both sides
-10= 9x + 10
3. Subtract 10 on both sides
-20= 9x
4. Divide by 9 on both sides
5. Your answer is
X= -20/9
