x + y = 3
x =6 - 4y
Solution
Use the top equation to substitute for x in the second equation.
x = 3 - y
Put this result into the second given equation and solve for y
3 - y = 6 - 4y Add 4y to both sides.
3 - y + 4y = 6 Combine on the left
3 + 3y = 6 Subtract 3 from both sides
3 - 3 + 3y = 6 - 3 Combine
3y = 3 Divide by 3
3y/3 = 3/3 Combine
y = 1
=========================
x + y = 3 but y = 1
x + 1 = 3 Subtract 1 from both sides.
x + 1 - 1 =3 - 1
x = 2
Answer
x = 2
y = 1
Answer:
he answer is 140 minutes to plant 14 saplings.
Step-by-step explanation:

Answer:
-6
Step-by-step explanation:
Because 2×(-6) is - 12
Step-by-step explanation:
x+13⁰+10x+13⁰+2x-2⁰= 180⁰
13x= 180-24
13x=156
x = 12⁰
now angle Q = 10x+13⁰
= 10(12)+13= 120+13
= 133⁰
Answer:
Step-by-step explanation:
The slope formula is 
Here, 
is -6, 
is 4, 
is -5, and 
is 4.
So, the slope of the line passing through the points (-6,-5) and (4,4) is .
