When working out an equation, if the result comes out like : x = 2, or y = 4.....a variable equal to a number, then there is 1 solution
if the result comes out like : 0 = 4, or 2 = 6...no variable and an incorrect result, then the equation has no solutions because ur lines are parallel.
if the result comes out like : 2 = 2 or 5 = 5...no variable and a true statement, then there will be infinite solutions because ur lines are coincident...they are the same line
Answer:
y=17
Step-by-step explanation:
4x+2y=70
x+y=26
2x+2y=52
2x=18
x=9
y=26-9
y=17
Answer:27x^6 /16
Step-by-step explanation:27x^3 x x^7 divided by 16x^4
then simplify the expression which will be 27x^3 x x^3 divided by 16
then calculate the product which is x^3 x x^3 which is x^6 so your answer is 27x^6/16.
