Answer:
x - y = 5
x + y = 23
x = 14, y = 9
Step-by-step explanation:
Make x subject:
x = 5 + y
Substitute c by (5 + y) :
( 5 + y) + y = 23
2y = 18
y = 9
Substitute y (9):
x = 5 + 9
x = 14

Answer:
3x³ + 16x² + 12x - 16
Step-by-step explanation:
(x - -4)(3x² + 4x - 4)
(x + 4) (3x² + 4x - 4)
3x³ + 4x² - 4x + 12x² + 16x - 16
3x³ + 4x² + 12x² - 4x + 16x - 16
3x³ + 16x² + 12x - 16
Answer:
x=3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(x+6)+x=x+45
(5)(x)+(5)(6)+x=x+45(Distribute)
5x+30+x=x+45
(5x+x)+(30)=x+45(Combine Like Terms)
6x+30=x+45
6x+30=x+45
Step 2: Subtract x from both sides.
6x+30−x=x+45−x
5x+30=45
Step 3: Subtract 30 from both sides.
5x+30−30=45−30
5x=15
Step 4: Divide both sides by 5.
5x
/5
