Simplifying 20pi = 2pi * r Multiply ip * r 20ip = 2ipr Solving 20ip = 2ipr Solving for variable 'i'. Move all terms containing i to the left, all other terms to the right. Add '-2ipr' to each side of the equation. 20ip + -2ipr = 2ipr + -2ipr Combine like terms: 2ipr + -2ipr = 0 20ip + -2ipr = 0 Factor out the Greatest Common Factor (GCF), '2ip'. 2ip(10 + -1r) = 0 Ignore the factor 2.Subproblem 1
Set the factor 'ip' equal to zero and attempt to solve: Simplifying ip = 0 Solving ip = 0 Move all terms containing i to the left, all other terms to the right. Simplifying ip = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Subproblem 2
Set the factor '(10 + -1r)' equal to zero and attempt to solve: Simplifying 10 + -1r = 0 Solving 10 + -1r = 0 Move all terms containing i to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + -1r = 0 + -10 Combine like terms: 10 + -10 = 0 0 + -1r = 0 + -10 -1r = 0 + -10 Combine like terms: 0 + -10 = -10 -1r = -10 Add 'r' to each side of the equation. -1r + r = -10 + r Combine like terms: -1r + r = 0 0 = -10 + r Simplifying 0 = -10 + r 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.
