Question

Solve the equation for y. Then find the value of y for each value of x. Y + 3x = 5; x = -1, 0, 3. Solve the equation for y.

Answer 1

5 - 3(-1)

Answer 2

To solve the equation for y, we need to isolate y on one side of the equation.

Starting with the equation Y + 3x = 5, we can subtract 3x from both sides to get:

Y = 5 - 3x

Now, we can substitute each value of x into the equation to find the corresponding value of y.

For x = -1:
Y = 5 - 3(-1)
Y = 5 + 3
Y = 8

For x = 0:
Y = 5 - 3(0)
Y = 5 + 0
Y = 5

For x = 3:
Y = 5 - 3(3)
Y = 5 - 9
Y = -4

So, the values of y for x = -1, 0, and 3 are 8, 5, and -4 respectively.

Answer 3

The expression 5 - 3(-1) simplifies as follows:

5 - 3(-1) = 5 - (-3)
= 5 + 3
= 8

Therefore, 5 - 3(-1) equals 8.
