Answer 3

ok thanks i was right just double checking

Answer 4

your welcome

Answer 5

3*2x+3*7 = 45
6x + 21 =45

Collect like terms - all constants on the Right Hand side
Solve by isolating X
Then divide both sides by the coefficient of X ; result answer for 1 X

Answer 6

ok thank u

Answer 7

Simplifying
3 * 2x + 3 * 7 = 45

Multiply 3 * 2
6x + 3 * 7 = 45

Multiply 3 * 7
6x + 21 = 45

Reorder the terms:
21 + 6x = 45

Solving
21 + 6x = 45

Solving for variable 'x'.

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

Add '-21' to each side of the equation.
21 + -21 + 6x = 45 + -21

Combine like terms: 21 + -21 = 0
0 + 6x = 45 + -21
6x = 45 + -21

Combine like terms: 45 + -21 = 24
6x = 24

Divide each side by '6'.
x = 4

Simplifying
x = 4
