substitute the ordered pair (2, 3 ) into the 2 equations
(3 × 2 ) + (4 × 3 ) = 6 + 12 = 18 → True
(2 × 2 ) - (2 × 3 ) = 4 - 6 = - 2 → False
Hence the ordered pair (2, 3 ) is not a solution to the system of linear equations.
When (2, 3 ) is substituted into the first equation, the equation is true.
When (2, 3 ) is substituted into the second equation, the equation is false.
5= (6+4)x
5= 10x
5= 10x then divide by 10 to get the variable by itself
__ ___
10 10
.5 = x you can use .5 or 1/2
hope this helps!

well 3x15= 45 and 15x17= 255 so 45+255= 300
