Answer:
x = 1/2
Step-by-step explanation:
4x - 3 + 5 = 2x + 7 - 8x
4x + 2 = -6x + 7
10x + 2 = 7
10x = 5
x = 5/10
x = 1/2
Answer:
9/10
Step-by-step explanation:
2n+3=12n-6
3=12n-2n-6
3=10n-6
10n=3+6
10n=9
n=9/10
Answer:
The correct answer is C. y = 3/4x - 12
Step-by-step explanation:
In order to find this, we must first note that the slope will be 3/4. We can tell this because parallel lines have the same slope. Next, we use that along with the point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - -18 = 3/4(x - -8)
y + 18 = 3/4 (x + 8)
y + 18 = 3/4x + 6
y = 3/4x - 12
3 is greater than -6. Therefore,
-6 < 3.
Y = 6x
4x + y = 7
(substitute y = 6x in the ‘y’ spot in 4x + y = 7)
4x + 6x = 7
10x = 7
/10 on both sides
x = 7/10
(substitute x = 7/10 in the ‘x’ spot in either of the two equations)
y = 6x
y = 6(7/10)
y = 4.2 = 21/5
Answer:
x = 7/10
y = 21/5
