Transposing/ Rearranging the subject

If m = 3, x = 2, and c = 1, calculate y:
y = mx + c

• 7
• 6
• 5
• 8

Make w the subject of

• w = A/l
• w = l/A
• w = A - l
• w = Al

Make x the subject of y = mx + 1

• x = (y - 1)/m
• x = y - 1/m
• x = y/m - 1
• x = my - 1

Make x the subject:
N = (180 + x)/2

• x = 2N -180
• x = N - 180
• x = N/2 -180
• x = N -180/2

Make r the subject:
C = 2πr

• r = C/2π
• r = C - 2π
• r = 2πC
• r = Cπ/2

Make r the subject:
A = πr²

• r = √(A/π)
• r = √Aπ
• r = Aπ²
• r = (Aπ)²

Solve P₁V₁ = P₂V₂ for V₁

• V₁ = P₂V₂/P₁

• V₁ = P₁/P₂V₂

Solve ΔG = ΔH - TΔS for ΔH

• ΔH = ΔG + TΔS

• ΔH = ΔG/(TΔS)

Solve c = λν for λ

• λ = c/ν

• λ = ν/c
