Answer:
(3x - 14) = (2x+ 10) { Because the angles are vertically opposite to each other}
3x-2x= 14+10
x=24

Answer:
2x³ + 11x² + 8x - 16
Step-by-step explanation:
Multiply:
(x + 4) (2x² +3x - 4)
2x³ + 3x² - 4x + 8x² + 12x - 16
Combine like terms:
2x³ + 11x² + 8x - 16
X= 6
Y= 0
Z= -2
CHECK
3x + y -2z =22
3(6) + 0 -2(-2) =22
18 + 0 +4= 22
22=22
x+5y+z =4
6 +5(0)+ -2 =4
6 + 0 +-2 = 4
4=4
x+3z=0
6 + 3(-2) =0
6 -6 = 0
0=0
