Q:
# 3x + 4y =10 6x -2y = 40

Accepted Solution

A:

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
