In the equation, 3x+y=2, if the value of x is 4, what is the value of y?
- 1
- 10
- -10
- None of these
Explanation
To find the value of y in the equation 3x+y=2, we can substitute the given value of x into the equation and solve for y.
1. Given value of x: x = 4.
2. Substitute the value of x into the equation: 3(4) + y = 2.
3. Simplify the equation: 12 + y = 2.
4. Solve for y by isolating the variable: y = 2 - 12.
5. Simplify the right side of the equation: y = -10.
Therefore, when the value of x is 4 in the equation 3x+y=2, the value of y is -10.
