you don't have enough info, we need to know how old he was when he was twice her age, or how old she was
3x + 11y = 4
2x + 6y = 0
I got
15/2, -5/4
Answer:
x = 10 cm
Step-by-step explanation:
(3x + 2) + (3x + 2) + (4x - 5) + (4x - 5) = 134 cm
combine like terms:
14x - 6 = 134
add 6 to each side of the equation:
14x = 140
divide both sides by 14:
x = 10
Answer:
x = 8/7
Step-by-step explanation:
