Answer:
(x,y)=(10,6)
Step-by-step explanation:
Substitute the value of x into the equation {4x+ 5= 70
{x= 6+ 2/3y
solve the equation 4(6+2/3y) +5y = 70
substitute the value of y into the equation y=6
solve the equation x=6 + 2/3 times 6
A possible solution is x= 10
Check the solution (x,y) = (10 ,6)
Simplify {4 times 10 + 5 times 6 =7
{3 times 10 - 2 times 6 = 18
The ordered pair is a solution {70 = 70
{18 =18
