Answer:
y = - 6 + 2x
Step-by-step explanation:
Given
4x - 2y = 12 ( subtract 4x from both sides )
- 2y = 12 - 4x ( divide all terms by - 2 )
y = - 6 + 2x
Answer:
I am not sure how your teacher wanted you to estimate the answer but I solved it for you. Hopefully this helps.
Step-by-step explanation:
7x-y=7
x+2y=6
14x-2y=14
x+2y=6
add both equations
15x=20
x=20/15
x=4/3
x+2y=6
4/3+2y=6
2y=6-4/3
2y=18/3 -4/3
2y=14/3
divide both sides by 2
y= 14/3 divided by 2
y=14/3(1/2)
y=14/6
2y=
Answer:
x = 25
Step-by-step explanation:
it's an isosceles triangle so base angles are the same
3x - 30 = 45
Add 30 on both sides
3x = 75
divide both sides by 3
x = 25
