Question

5x+3y=-16
-10x-3y=11

Answer 1

Explanation:

5x+3y=16

-10x-3y=11

=-5x=-27

x=5.4

substitute x=5.4 into equation 1

5x+3y=-16

5(5.4)+3y=-16

27+3y=-16

27+16=3y

43=3y

y=14.3333

Answer 2

Answer:

Simplifying
5x + 3y = 16

Solving
5x + 3y = 16

Solving for variable 'x'.

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

Add '-3y' to each side of the equation.
5x + 3y + -3y = 16 + -3y

Combine like terms: 3y + -3y = 0
5x + 0 = 16 + -3y
5x = 16 + -3y

Divide each side by '5'.
x = 3.2 + -0.6y

Simplifying
x = 3.2 + -0.6y
