Question

1) 3x+8x=122)2(4x+5)=16​

Answer 1

Ответ: 1)x= 12/11

2)x= 3/4

Пошаговое объяснение:

1) 3x+8x=12

x= 12/11

2)8x+10=16

  8x=6

  x= 3/4

Answer 2

Let's solve each equation step by step:

1. $3x + 8x = 12$ Combine like terms: $11x = 12$

Now, isolate $x$ by dividing both sides by 11: $x = \frac{12}{11}$

2. $2(4x + 5) = 16$ Distribute the 2: $8x + 10 = 16$

Now, isolate $x$ by subtracting 10 from both sides: $8x = 6$

Next, divide both sides by 8 to solve for $x$: $x = \frac{6}{8}$

Simplify the fraction: $x = \frac{3}{4}$
