Question

4X+18=26-2X 2x+5=2(х+1)+11 (y+4)-(y-1)=6y лінійне рівняння

Answer 1

(y+4)-(y-1)=6y 4X+18=26-2X    
4X+2X=26-18
6X=8
X=8/6
2x+5=2(х+1)+11
2x+5=2x+2+11
0=8 рівняння немає розвязку
(y+4)-(y-1)=6y
у+4-у+1=6у
-6у=-5
-у=-5/6 або 5/6

Answer 2

To solve each of these linear equations, we'll use standard algebraic techniques:

1. 4X + 18 = 26 - 2X

First, we'll combine like terms on each side of the equation:

6X + 18 = 26

Then, we'll subtract 18 from each side:

6X = 8

Finally, we'll divide both sides by 6:

X = 4/3

2. 2x + 5 = 2(x + 1) + 11

First, we'll distribute the 2 on the right side of the equation:

2x + 5 = 2x + 2 + 11

Next, we'll combine like terms on the right side of the equation:

2x + 5 = 2x + 13

Then, we'll subtract 2x from each side:

5 = 13

Since this equation is impossible, there is no solution.

3. (y + 4) - (y - 1) = 6y

First, we'll simplify the left side of the equation by distributing the negative sign:

y + 4 - y + 1 = 6y

Next, we'll combine like terms on the left side of the equation:

5 = 6y

Finally, we'll divide both sides by 6:

y = 5/6

Therefore, the solution to the third equation is y = 5/6.
