x = 1
y =x +3
y=4
If X = 1, then substitute 1 for X in y = x + 3.
1 + 3 = 4
y = 4
To solve the equation and find the value of y, substitute the value of x into the equation and perform the addition:
Substituting the value of x, which is 1, into the equation:
y = 1 + 3
Adding 1 and 3:
y = 4
Therefore, the value of y is 4.
