Question

me ajudem é para amanhã
3(x+4)+1=2(2x+7)
2x+3(x-1)=4x+12​

Answer 1

Resposta:

3(x+4)+1=2(2x+7)

Step 1: Simplify both sides of the equation.

3(x+4)+1=2(2x+7)

(3)(x)+(3)(4)+1=(2)(2x)+(2)(7)(Distribute)

3x+12+1=4x+14

(3x)+(12+1)=4x+14(Combine Like Terms)

3x+13=4x+14

3x+13=4x+14

Step 2: Subtract 4x from both sides.

3x+13−4x=4x+14−4x

−x+13=14

Step 3: Subtract 13 from both sides.

−x+13−13=14−13

−x=1

Step 4: Divide both sides by -1.

-x/-1=1/-1

X=-1

Answer:

x=−1

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

2x+3(x−1)=4x+12

Step 1: Simplify both sides of the equation.

2x+3(x−1)=4x+12

2x+(3)(x)+(3)(−1)=4x+12(Distribute)

2x+3x+−3=4x+12

(2x+3x)+(−3)=4x+12(Combine Like Terms)

5x+−3=4x+12

5x−3=4x+12

Step 2: Subtract 4x from both sides.

5x−3−4x=4x+12−4x

x−3=12

Step 3: Add 3 to both sides.

x−3+3=12+3

x=15

Answer:

x=15

Explicação passo a passo:

Answer 2

Resposta:

3(x+4)+1=2(2x+7)

3x+12+1=4x+14

3x-4x=14-12+1

-x=1 (-1)

x≠-1

2x+3(x-1)=4x+12

2x+3x-3=4x+12

5x-3=4x+12

5x-4x=12+3

X=15

Explicação passo-a-passo:

multiplica 3 com os números que estão dentro de patentes que temos (x+4),

então será , 3(x+4)= 3x+12
