5x + 51 = 9x + 11 Becomes 40 = 4x So x = 10
3x-5+2x=-49 is the same as 5x=-44 or x=-44/5
5x plus 3 does equal 3 plus 5x; commutative law.

5x + 51 = 9x + 11 Becomes 40 = 4x So x = 10
3x-8+5x+39+4x+51 = x(3+5+4) + -8 + 39 + 51 = 12x +82
5x + 6 = -44 ⇒ 5x = -50 (subtract 6 from both sides) ⇒ x = -10 (divide both side by 5)
3x-5+2x=-49 is the same as 5x=-44 or x=-44/5
5x+33=112x-51, deduct 5x from each side of the equation leaves 33=107x-51, add 51 to each side leaves 84=107x, divide both sides by 107 gives answer x=84/107

5x plus 3 does equal 3 plus 5x; commutative law.
y = 3x 5x + 2y = 44 substitute 3x for y into the second equation 5x + 2(3x) = 44 5x + 6x = 44 11x = 44 divide by 11 to both sides x = 4 y = 3x substitute 4 for x y = 3(4) = 12 So the solution for the system is the intersection point (4, 12).
