1..) 2x +15 = 35 
Masja [62]

Answer:

1) x=10

2) x=3

Step-by-step explanation:

1)

2x+15=35

Subtract 15 from both sides

2x=20

Divide both sides by 2

x=10

2(10)+15=35

20+15=35

35=35

this shows that 10 is the right answer

2)

7x-3=18

Add 3 to both sides

7x=21

Divide both sides by 7

x=3

7(3)-3=18

21-3=18

18=18

this shows that 3 is the right answer

Hope this helps

Solve for the x using elimination <br> 3x-2y=13x−2y=1 <br> 2x+2y=42x+2y=4
Nikitich [7]

3x - 2y = 1

2x + 2y = 4

Add the second equation to the first

5x     = 5

2x + 2y = 4

Divide the first equation by 5

x        = 1

2x + 2y = 4

Subtract the first equation from the second

x        = 1

x + 2y = 3

Subtract the first equation from the second again

x        = 1

   2y = 2

Divide the second equation by 2

x        = 1

      y = 1

<h3>So, the solution is  x = 1  and  y = 1  {or: (1, 1)} </h3>
