Question

Solve for y: 4x + 6y = 16 and x = -2

a) y = -4
b) y = 4
c) y = -2
d) y = 2​

Answer 1

Answer:

Simplifying

4x + -6y = 16

Solving

4x + -6y = 16

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '6y' to each side of the equation.

4x + -6y + 6y = 16 + 6y

Combine like terms: -6y + 6y = 0

4x + 0 = 16 + 6y

4x = 16 + 6y

Divide each side by '4'.

x = 4 + 1.5y

Simplifying

x = 4 + 1.5y

Answer 2

Step-by-step explanation:

4x+6y=16

X=-2

Filling the value of x in given equation

4 x-2 + 6y = 16

-8+6y=16

6y=16+8

Y=24/6

Y =4
