Solve the equations and check yourresult-3 + 2× = 1-×

Answer»

Hello!

Answer:

$It\:\:is: x=\frac{-2}{3}$

Step-by-step explanation:

$3 + 2x = 1 - x$

We GROUP similar numbers:

$2x + x= 1-3$

We ADD and SUBTRACT:

$3x=-2$

The "3" happens to DIVIDE:

Check:

$3 +2\cdot \frac{-2}{3}= 1 - \frac{-2}{3}\\\\3 + -\frac{4}{3}= \frac{5}{3}\\\\\frac{5}{3} =\frac{5}{3}$

Si es correcto ✔

\angle B=40^{\circ}∠B=40

\angle A=20^{\circ}∠A=20

∘

Step-by-step explanation:

In triangle ABC

\angle C=3\angle B=2(\angle A+\angle B)∠C=3∠B=2(∠A+∠B)

\angle A+\angle B=\frac{1}{2}\angle C∠A+∠B=

∠C

\angle B=\frac{1}{3}\angle C∠B=

3

1

∠C

\angle A+\angle B+\angle C=180^{\circ}∠A+∠B+∠C=180

∘

By USING triangle angles SUM property

Substitute the VALUES then we get

\frac{1}{2}\angle C+\angle C=180

2

1

∠C+∠C=180

\frac{\angle C+2\angle C}{2}=180

2

∠C+2∠C

=180

\frac{3}{2}\angle C=180

∠C=180

\angle C=\frac{180\times 2}{3}=120^{\circ}∠C=

180×2

=120

\angle C=120^{\circ}∠C=120

Substitute the values then we get
