What is the answer 3x+(x-8)=120

1 answer:

8 0

Combine like terms.

3x+(x-8)= 120

4x-8= 120

Add 8 to both sides.

4x= 128

Divide by 4 into both sides.

x= 32

I hope this helps!

I would use subsitution because both are already equal to a single variable

set both equal since both equal y
8x-9=y=4x-1
8x-9=4x-1
minus 4x both sides
4x-9=-1
add 9 boh sides
4x=10
divide by 4
x=10/4=5/2
sub for x

y=4x-1
y=4(10/4)-1
y=10-1
y=9

(5/2,9) is solution

A. work shown above
B. (5/2,9) or (2.5,9)

The value of x is equal to 1.5.

It is required to find x.

<h3>What is quadratic equation?</h3>

Any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power. The quadratic formula to solve a quadratic equation ax2 + bx + c = 0 is x = [-b ± √(b2 - 4ac)]/2a.

Given that:

So for the triangle, the perimeter would be:

$(x^{2} +x+3)+(x^{2} +2x-2)+(x^{2} +2x-9)=4$
