Answer:
(1,2)
y=2
x=1
Step-by-step explanation:
x+y=3
3x+5y=13
solve the equation
x=3-y
3x+5y=13
substitute the value of x into an equation
3(3-y)+5y=13
distribute
9-3y+5y=13
add -3y to 5y
9+2y=13
subtract 9 from both sides
2y=4
divide both sides by 2
y=2
substitute the value of y into an equation
x=3-2
subtract 3 to 2
x=1

Answer: The answer for x is 28.
Step-by-step explanation: Divide 70 by 10 and you get 7, which is the slope. Then multiply 4x7 and that gets you 28!
2 and 2/3 + 4 and 3/4 is equal to 7 and 5/12
