Mathematics

Ahat [919]3 years ago

Answer:

Step-by-step explanation:

z = 3

2y + z = 1

2y + 3 = 1        {substituting z =3}

2y = 1 -3

2y = -2

y = - 2/2

y = -1

2x +3y +2z = 13

2x + 3 * (-1) + 2*3 = 13      { {substituting z =3} and y = -1}

2x -3 + 6 =13

2x + 3 = 13

2x  = 13 - 3

2x= 10

x = 10/2

x = 5

The sum of three consecutive even integers is 126. Let x represent the first integer, x + 2 represent the second integer, and x
LekaFEV [45]
We have that (x) + (x+2) + (x+4) = 126 so 3x + 6 = 126 can be used to find the first integer.

3x + 6 = 126
3x = 120
x = 40

The numbers are 40, 42, 44

X/2=1.2 <br> Solve for x and check.
tatuchka [14]

Answer: X = 2.4

Step-by-step explanation:

The first step should be to isolate x or get x alone. This means we should get rid of the divided by 2 on the left by multiplying both sides by 2. This would get us to 2 * X/2 = 1.2 * 2. The multiplying X/2 would simplify to just X, and the 1.2 * 2 = 2.4. Therefore the final equation would become X = 2.4.

To check, you would plug in 2.4 into where X is in X/2 = 1.2. Since 2.4/2 = 1.2, we know that X = 1.2 from checking.
