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.
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

When x=0, the value of y is
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.
2(0) - 7y = 19
-7y = 19
y = 19 / -7
y ≈ -2.714
Therefore, when x = 0, y is approximately -2.714.
Solve the equation for u.
up + un=t
up + un=t
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).
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).
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).
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).
