Tbh, might be wrong on this one. I'm on the road so didn't double-check my answer.
Answer:
The resulting equation is
x^2/4+16x^2/9=1
Step-by-step explanation:
The given equations are:
3y=12x eq(1)
x^2/4+y^2/9=1 eq(2)
We need to isolate variable y in equation 1
Divide both sides of the equation with 3
3y/3 = 12x/3
y = 4x
Now, substitute the value of y=4x in second equation
x^2/4+y^2/9=1
x^2/4 + (4x)^2/9 = 1
The resulting equation is
x^2/4+16x^2/9=1
Answer:
x≈ -4.71
Step-by-step explanation:
7(x+6)=9
Distribute the 7 into the parenthesis.
7x+ 7(6)= 9
Multiply the numbers.
7x+ 42= 9
Subtract from both sides.
7x+42= 9
-42 -42
Now, divide to both sides.
<u> 7x</u>= <u>-33</u>
7 7
x= -4.71428571429
x≈ -4.71
