I need help please somebody answer ASAP please I’d highly appreciate it

2.(b) w= 3

3. x= -3 or x= 3

Step-by-step explanation:

2.(b) Method 1:

Simplify:

×5 on both sides:

Expand:

Bring constants to 1 side, w terms to the other:

Simplify:

Divide both sides by 3:

Method 2:

Multiply by 5 throughout:

Expand:

Simplify:

+9 on both sides:

-4w on both sides:

Simplify:

Divide by 3 on both sides:

3.

Multiply by 3x on both sides:

Expand:

Simplify:

Divide by 6 on both sides:

-9 on both sides:

Factorise:

*Since a²-b²= (a +b)(a -b),

Thus,

x +3= 0 or x -3= 0

x= -3 or x= 3

w = 3

Step-by-step explanation:

(6x-12)/3 + 4 = 18/x

Simplify fraction

2x -4 +4 = 18/x

Combine -4+4=0 Divide by 2 to reduce

x = 9/x

Multiply both sides by x

x² = 9

x = 3, -3

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
