Find the value of y in each formula if x= -3.
y + 1 = 2(x - 5)
Substitute -3 for x.
The first step leaves you with this:
y + 1 = 2 * (-8) = -16
Now solve for y by subtracting 1 from each side of the equation.
To find the value of y in the equation y + 1 = 2(x - 5) when x = -3, you need to substitute -3 for x first.
Start by substituting -3 for x in the equation:
y + 1 = 2(-3 - 5)
Simplify the equation inside the parentheses:
y + 1 = 2(-8)
Multiply 2 by -8:
y + 1 = -16
Now, to solve for y, subtract 1 from both sides of the equation:
y + 1 - 1 = -16 - 1
Simplifying further:
y = -17
So, the value of y in the given formula when x = -3 is -17.
