Simplifying 42x + 7y = 63forx Solving 42x + 7y = 63forx Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-63forx' to each side of the equation. 42x + -63forx + 7y = 63forx + -63forx Reorder the terms: -63forx + 42x + 7y = 63forx + -63forx Combine like terms: 63forx + -63forx = 0 -63forx + 42x + 7y = 0 Add '-7y' to each side of the equation. -63forx + 42x + 7y + -7y = 0 + -7y Combine like terms: 7y + -7y = 0 -63forx + 42x + 0 = 0 + -7y -63forx + 42x = 0 + -7y Remove the zero: -63forx + 42x = -7y Combine like terms: -7y + 7y = 0 -63forx + 42x + 7y = 0 Factor out the Greatest Common Factor (GCF), '7'. 7(-9forx + 6x + y) = 0 Ignore the factor 7.Subproblem 1
Set the factor '(-9forx + 6x + y)' equal to zero and attempt to solve: Simplifying -9forx + 6x + y = 0 Solving -9forx + 6x + y = 0 Move all terms containing x to the left, all other terms to the right. Add '-1y' to each side of the equation. -9forx + 6x + y + -1y = 0 + -1y Combine like terms: y + -1y = 0 -9forx + 6x + 0 = 0 + -1y -9forx + 6x = 0 + -1y Remove the zero: -9forx + 6x = -1y The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
