Solve the simultaneous equation x=y+1
x+2y=7
To solve this system of equations, we will substitute the first equation into the second equation:
Substitute x=y+1 into x+2y=7:
(y+1) + 2y = 7
y + 1 + 2y = 7
3y + 1 = 7
3y = 6
y = 2
Now that we have found the value of y, we can substitute it back into the first equation to solve for x:
x = 2 + 1
x = 3
Therefore, the solution to the simultaneous equations x=y+1 and x+2y=7 is x=3 and y=2.
