Solving Equations for a Variable

Rewrite this formula and solve for the variable y. 18x - 3y = 27

• y = -6x + 9

• y = -6x - 9

• y = 6x + 9

• y = 6x - 9

Rewrite this formula and solve for the variable y. x/2 + y/5 = 1

• y = -5/2 x + 5

• y = 5/2 x + 5

• y = -5/2 x + 2

• y = -5/2 x + 1/2

Rewrite this formula and solve for the variable r. d = r × t

• r = d - t

• r = t - d

• r = t / d

• r = d / t

Rewrite this formula and solve for the variable p. i = p × r × t

• p = i - r - t

• p = r t / i

• p = i / r t

• p = ( i - r ) / t

Rewrite this formula and solve for the variable r. C = 2πr

• r = 2π / C

• r = C - 2 - π

• r = C - 2π

• r = C / 2π

Rewrite this formula and solve for the variable W. P = 2L + 2W

• W = P/2 - 2L

• W = P - 2L

• W = (2L - P) / 2

• W = (P - 2L) / 2

Rewrite this formula and solve for the variable C. F = 9/5 ⋅ C + 32

• C = 5/9 ⋅ F + 32

• C = 5/9 (F - 32)

• C = 5/9 (F + 32)

• C = 5/9 ⋅ F - 32

Rewrite this formula and solve for the variable h. A = ½ b h

• h = 2A / b

• h = A - ½b

• h = 2A - b

• h = A / b
