3x + 4y =10 6x -2y = 40

Answers

Answer 1
Answer:

Simplifying

3X + 10 = 6X + 40

Reorder the terms:

10 + 3X = 6X + 40

Reorder the terms:

10 + 3X = 40 + 6X

Solving

10 + 3X = 40 + 6X

Solving for variable 'X'.

Move all terms containing X to the left, all other terms to the right.

Add '-6X' to each side of the equation.

10 + 3X + -6X = 40 + 6X + -6X

Combine like terms: 3X + -6X = -3X

10 + -3X = 40 + 6X + -6X

Combine like terms: 6X + -6X = 0

10 + -3X = 40 + 0

10 + -3X = 40

Add '-10' to each side of the equation.

10 + -10 + -3X = 40 + -10

Combine like terms: 10 + -10 = 0

0 + -3X = 40 + -10

-3X = 40 + -10

Combine like terms: 40 + -10 = 30

-3X = 30

Divide each side by '-3'.

X = -10

Simplifying

X = -10

Is 52L greater than 5,200mL?

Answers

1L = 1,000mL

therfore

52L = 52 × 1,000mL = 52,000 mL

52L = 52,000mL !!!!
5200mL → 520 cL → 52dL → 5.2L

Example:

If

1L ------ 1000mL
x -------- 5200mL

1000x = 5200
x = (5200)/(1000)
x = 5,2

Therefore:
52L > 5200mL or 5.2L (True)

    - 0.592  .

Just in case you actually intended to write "add to -11 and multiply to 18",
then the two numbers are
