Question

Solve the equation for y. Then find the value of y for each value of x.

2x-7y=19;x=-1,0,1
When x​,=-1 the value of y is

Answer 1

[AI-generated answer — Bot GPT 3.5]

When x = -1, we substitute this value into the equation and solve for y:

2(-1) - 7y = 19
-2 - 7y = 19
-7y = 19 + 2
-7y = 21
y = 21 / -7
y = -3

Therefore, when x = -1, y = -3.

Answer 2

When x=0​, the value of y is

Answer 3

When x = 0, we substitute this value into the equation and solve for y:

2(0) - 7y = 19
-7y = 19
y = 19 / -7
y ≈ -2.714

Therefore, when x = 0, y is approximately -2.714.

Answer 4

Solve the equation for u.

up + un=t

Answer 5

To solve the equation for u, we need to isolate the variable u on one side of the equation. Since up and un are both terms with u, we can factor out u from both terms:

u(p + n) = t

Next, we divide both sides of the equation by (p + n) to solve for u:

u = t / (p + n)

Therefore, the equation for u is u = t / (p + n).

Answer 6

Use the distributive property

Apologies for the oversight. We'll use the distributive property to solve the equation for u.

up + un = t

Using the distributive property, we can rewrite the left side of the equation as:

u(p + n) = t

Next, we divide both sides of the equation by (p + n) to solve for u:

u = t / (p + n)

Therefore, the equation for u remains u = t / (p + n).
