Question

Liner systems of equations

Answer 1

8 years

Explanation:

x years later type A and type B will have the same height

Type A = Type B: 10 + (8/12)*X = 6 + (14/12)*X

multiply 12 each side

120 + 8x = 72 + 14x

14x - 8x = 120 - 72

6x = 48

x = 8

check: A: 10 x 12 + 8 x 8 = 184

B: 6 x 12 + 14 x 8 = 184
