The value of x in this system of equations is 1

3x + y = 9
y=-4x + 10
1. Substitute the value of y in the first equation
2. Combine like terms
3. Apply the subtraction property of equality
4. Apply the division property of equality

Answer:

(1, 6)

Explanation:

If x = 1 then the first equation is 3(1) + y = 9, and so y = 6. The second equation is y = -4(1) + 10, or y = 6.

Thus, the solution to this system of equations is (1, 6).
