a - 5 = 30
Step-by-step explanation:
here is your answer
Answer: your answer should be 10.5130
Step-by-step explanation:
<span>y-2x=-6 and 5x-y=9
step 1: isolate y in the first equation
y = 2x - 6
step 2: substitute the y value on the 2th equation:
5x-(2x-6)=9
step 3: solve the present equation:
5x - 2x + 6 = 9
3x = 9-6
3x = 3
x = 1
step 4: get the y value by replacing the value of x in </span>y = 2x - 6:
<span>
y = 2*1 - 6
y = 2 - 6
y = -4
S={1, -4}

51, because 39+12=51. You just add both parts of the tree. Please Rate Brainliest.
Yes because 4x3^x =12^x since the coefficient is added to the answer because it is in the 3.
