Question

(7-x).8=4x+13x+15x=67a-18a+37=​

Answer 1

Ответ:

1) $=5.6-0.8x$

2) $=32x$

3) $=49a+37$

объяснение:

1) $\left(7-x\right)\cdot \:0.8$

$=0.8\left(7-x\right)$

$=0.8\cdot \:7-0.8x$

$=5.6-0.8x$

2) $4x+13x+15x$

$=32x$

3) $67a-18a+37$

$=49a+37$

Answer 3

To solve the equation, let's simplify each expression step by step:

1. (7 - x) * 8 = 4x + 13x + 15x

First, distribute the 8 to the terms inside the parentheses:

56 - 8x = 4x + 13x + 15x

2. Combining like terms on the right side:

56 - 8x = 32x

3. Move all terms involving x to one side of the equation:

56 = 32x + 8x

Combining the x terms:

56 = 40x

4. Solve for x by dividing both sides of the equation by 40:

56/40 = x

Simplifying:

7/5 = x

So, the value of x is 7/5 or 1.4.

Now let's solve the second equation:

5x - 18a + 37 = 0

To solve for a, we need more information or an additional equation involving 'a'.
