Question

solve the equation graphically X + Y is equal to 10 Y is equal to X + 4​

Answer 1

First, this question is not clear as I was unable to identify the 2 separate equations.

Second, this is a MATHS question and you asked it with title of a- English question.

Answer 2

x+y=10.........1

y=x+4............2

x+(x+4)=10.......from eqn 1

2x+4=10

2x=6

x=3

y=x+4=3+4=7

x=3

y=7
