Question

Se poderem me ajudar a conta 4x-2x=3x + 4 quero o valor de x e a conta toda armada

Answer 1

Resposta:

4x−2x=3x+4

Step 1: Simplify both sides of the equation.

4x−2x=3x+4

4x+−2x=3x+4

(4x+−2x)=3x+4(Combine Like Terms)

2x=3x+4

2x=3x+4

Step 2: Subtract 3x from both sides.

2x−3x=3x+4−3x

−x=4

Step 3: Divide both sides by -1.

−x/−1=4/−1

x=−4 resposta!
