HELP ME! Write an equation where a number is added to a variable, and a solution is -8.

Write an equation where a number is multiplied by a variable, and a solution is - 4/5 (negative four fifths)

also dont answer if you don't know

Let the variable be x

A number isn’t given so pick any number.

Let’s use 10

Set up the equation to get:

X + 10 = -8

Solve for the variable by subtracting 10 from both sides:

X = -18

Let the variable be y and pick any number, let’s use the number 2.

Equation: 2 x y = 4/5

Solve for y by dividing both sides by 2:

Y = 2/5

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14
