Solve the system of equations for 7x+2y=16 and -21x-6y=24

Mathematics

Georgia [21]3 years ago
6 0
Simplifying
7x + 2y = 16

Solving
7x + 2y = 16

Solving for variable 'x'.

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

Add '-2y' to each side of the equation.
7x + 2y + -2y = 16 + -2y

Combine like terms: 2y + -2y = 0
7x + 0 = 16 + -2y
7x = 16 + -2y

Divide each side by '7'.
x = 2.285714286 + -0.2857142857y

Simplifying
x = 2.285714286 + -0.2857142857y

9x = 52 . . . . . . . . . . . add 5

x = 52/9 = 5 7/9
