Question

6) 2 - x = 1,376;7) (234 + x) - 456 = 178;​

Answer 1

Ответ:

2-x=1,376

-x=1,376-2

x=0,624

(234+x)-456=178

234+x-456=178

x=178-234+456

x=400

Answer 2

Ответ:

2 - x = 1,376

-х + 2 = 1,376

-х = - 0,624

х=0,624

Пошаговое объяснение:

(234+х)-456=178

234+х=178+456

234+х=634

х=634-234

х=400

Answer 3

Let's solve the equations:

6. $2 - x = 1,376$:

Subtract 2 from both sides:

$-x = 1,376 - 2$

$-x = 1,374$

Multiply both sides by -1 to isolate x:

$x = -1,374$

So the solution to the first equation is $x = -1,374$.

7. $(234 + x) - 456 = 178$:

Combine like terms within the parentheses:

$234 + x - 456 = 178$

Combine numbers on the left side:

$x - 222 = 178$

Add 222 to both sides:

$x = 400$

So the solution to the second equation is $x = 400$.
