Answer:
3-(X) +2 -(Y)
Step-by-step explanation:
Answer:
x = 7
y = 4
Step-by-step explanation:
3x - 5 = 5y - 4 (sides of an equilateral ∆)
3x - 5y = 5 - 4
3x - 5y = 1 ----› Eqn. 1
3x - 5 = y + 12 (sides of an isosceles ∆)
3x - y = 5 + 12
3x - y = 17 ---› Eqn. 2.
Subtract eqn 2 from eqn 1.
3x - 5y = 1 ----› Eqn. 1
3x - y = 17 ---› Eqn. 2.
-4y = -16
Divide both sides by -4
y = 4
Substitute y = 4 into eqn. 2
3x - y = 17 ---› Eqn. 2.
3x - 4 = 17
3x = 17 + 4
3x = 21
Divide both sides by 3
x = 7
