Answer: C
Step-by-step explanation: The number go larger in value
Simple the answer is: n=14
Answer:
Step-by-step explanation:
Step 1: y=3x
x+2y=21
Step 2: x+2(3x)=21 (x+6x=21)
Substitute the "y" in the second equation with the "3x."
Step 3: (7x=21)
Combine like terms
Step 4: x=3
Divide
Step 5: y=3(3) or y=9
Plug in your answer to find the value of "y"
Answer: -4
Step-by-step explanation: I am guessing you meant ...99 + 2(8*3)...
3x + 99 + 2(8 x 3) = 135
3x + 99 + 2(24) = 135
3x + 99 +48 = 135
3x + 147 = 135
(3x + 147) - 147 = (135) - 147
3x = -12
(3x) ÷ 3 = (-12) ÷ 3
x = -4
