Question

А)2,6+7x=6,8 б)x:6+2,8=3,7

Answer 1

Ответ:

7x=6.8-2.6

7x=4.2

x=4.2/7

x=0.6

x:6+2,8=3,7

х:6=3,7-2,8

х:6=0,9

х=6*0,9

х=5,4

Answer 2

Let's solve the equations step by step:

A) 2.6 + 7x = 6.8

Step 1: Subtract 2.6 from both sides to isolate the variable term: 2.6 + 7x - 2.6 = 6.8 - 2.6 7x = 4.2

Step 2: Now, divide both sides by 7 to solve for x: x = 4.2 / 7 x = 0.6

So the solution for the first equation is x = 0.6.

B) x/6 + 2.8 = 3.7

Step 1: Subtract 2.8 from both sides to isolate the fraction term: x/6 + 2.8 - 2.8 = 3.7 - 2.8 x/6 = 0.9

Step 2: To solve for x, multiply both sides by 6 to get rid of the fraction: 6 * (x/6) = 6 * 0.9 x = 5.4

So the solution for the second equation is x = 5.4.

Final solutions: A) x = 0.6 B) x = 5.4
