The two equations given in the question are
y = - x + 5
and
5x + 2y =14
Now we will have to put the value of y from the first equation in the second equation and then calculate.
5x + 2y = 14
5x + 2(-x + 5) = 14
5x - 2x + 10 = 14
3x = 14 - 10
3x = 4
x = 4/3
Now we have to put the value of x in the first equation for determining the value of y
y = - x + 5
= - (4/3) + 5
= (15 - 4)/3
= 11/3
So the value of x is 4/3 and the value of y is 11/3.
You see how many times 65 goes into 325 it will take a while if you just go 65+65 all the way up to 325. You will take the 65 under the 325 so now it will be 325-65 and you subtract it then solve like any other long division problem. Divide. Multiply, Subtract. Bring Down.
4b=a then plus 10 to see if the age holds true to 3b=a in ten years. Then since the question is how old is she today? You must either add 6 to young age (of20) or minus 4 from the older (of 30).
So Betty would be 26 today.
Answer: The answer is 10/27
Step-by-step explanation:
5 = 6q - 30 - 19
5 = 6q - 49
54 = 6q
9 = q
