Value 14 so it must be 55 or something
The last digit in the product will be '0' because anything multiplied by zero will be zero. In this case you are using larger numbers, however this will always be the case when multiplying with any number with zero.
Answer: 3
Step-by-step explanation: Simplifying
2(x + -3) + 9 = 3(x + -1) + x
Reorder the terms:
2(-3 + x) + 9 = 3(x + -1) + x
(-3 * 2 + x * 2) + 9 = 3(x + -1) + x
(-6 + 2x) + 9 = 3(x + -1) + x
Reorder the terms:
-6 + 9 + 2x = 3(x + -1) + x
Combine like terms: -6 + 9 = 3
3 + 2x = 3(x + -1) + x
Reorder the terms:
3 + 2x = 3(-1 + x) + x
3 + 2x = (-1 * 3 + x * 3) + x
3 + 2x = (-3 + 3x) + x
Combine like terms: 3x + x = 4x
3 + 2x = -3 + 4x
Solving
3 + 2x = -3 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
3 + 2x + -4x = -3 + 4x + -4x
Combine like terms: 2x + -4x = -2x
3 + -2x = -3 + 4x + -4x
Combine like terms: 4x + -4x = 0
3 + -2x = -3 + 0
3 + -2x = -3
Add '-3' to each side of the equation.
3 + -3 + -2x = -3 + -3
Combine like terms: 3 + -3 = 0
0 + -2x = -3 + -3
-2x = -3 + -3
Combine like terms: -3 + -3 = -6
-2x = -6
Divide each side by '-2'.
x = 3
Simplifying
x = 3
