You distribute the 30x to the equation in parenthesis

So basically you are doing (30x*x)+(30x*-3)
So you get 30x^2-90x

Hope this helps!

30x(x-3)
lets substitute x for 1
30 * 1(1 - 3)
1 - 3 = 2
30 * 1 = 30
30 * 2 = 60
I hope I did it correctly.

Caitlyn needs to solve the equation: 2(3x+1)=3(2-x). after copying the problem correctly she uses the Properties of Algebra to s

astra-53 [7]

Answer:

x=49

Step-by-step explanation:

2(3x+1)=3(2−x)

Step 1: Simplify both sides of the equation.

2(3x+1)=3(2−x)

(2)(3x)+(2)(1)=(3)(2)+(3)(−x)(Distribute)

6x+2=6+−3x

6x+2=−3x+6

Step 2: Add 3x to both sides.

6x+2+3x=−3x+6+3x

9x+2=6

Step 3: Subtract 2 from both sides.

9x+2−2=6−2

9x=4

Step 4: Divide both sides by 9.

9x9=49

x=49
