Answer:
x = -6
Step-by-step explanation:
-11 - 8x = -3x + 19 (Move constants to right side)
-8x = -3x + 19 + 11 (Move x to left side)
3x - 8x = 30 (simplify)
-5x = 30 (divide both sides by -5)
x = -6
From the system of equations, we have 3 unknowns and 3 equations. Therefore, it can be solved.
<span>3x - 2y + 2z = 30 (1)
</span><span>-x + 3y - 4z = -33 (2)
</span><span>2x - 4y + 3z = 42 (3)
We can write equation 2 x as a function of y and z and substitute the new equation to the other equations.
</span>x =3y - 4z + 33 (2)
3 (3y - 4z + 3)<span> - 2y + 2z = 30 (1)
</span>2 (3y - 4z + <span>3)</span> - 4y + 3z = 42 (3)
We simplify and solve the equations and we get values,
x = 4
y = -7
z = 2
