Answer:
(0,3)
y=3
x=0
Step-by-step explanation:
x+5y=15
-3x+2y=6
solve the equation
x=15-5y
-3x+2y=6
substitute the value of x into an equation
-3(15-5y)+2y=6
distribute
-45-15y+2y=6
add 15 to 2
-45-17y=6
add 45 from both sides
17y=51
divide both sides by 17
y=3
substitute the value of y into an equation
x=15-5•3
multiply 5 to 3
x=15-15
subtract
x=0

Answer:
10. 2x+y
11. x^2-15x+3
Step-by-step explanation:
10. when u add 7x+3y and 4x+4y you will get 11x+7y. 13x+8y minus 11x+7y will be 2x+y
11. when u add 3x^2+7x+1 and x^2-x+1 u will get 4x^2+6x+2. 5x^2-9x+5 minus 4x^2+6x+2 will be x^2-15x+3
