H + J = 12
If J is twice as big as H, Calculate the values of the numbers H and J
J = 2H
Substitute this value for J into the original equation
H + 2H = 12
3H = 12
Divide both sides by 3
H = 4
J = 2H = 2 × 4 = 8
L + M = 11
If M is 3 more than L, Calculate the values of the numbers M and L
M = L + 3
Substitute this value for M into the original equation
L + L + 3 = 11
Subtract 3 from both sides
2L = 8
Divide both sides by 2
L = 4
M = L + 3 = 4 + 3 = 7
