3.5x^3-2.3x^2+1.4x+15.6-1.2x^3+4.5x ^2-0.3x-3.2

Hello

Step-by-step explanation:

1) 11x^2y^2+7xy

2) 2.3x^3−2.3x^2+1.4x+15.6

3) −2x^2−2xy+5x+7y−4

4) 9x−13y−1

6) ax+bx−cx (stays the same)

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

x=5

step-by-step explanation:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
