what is the solution to the system of equations by using substitution?
3x - 2y = 5 ------ Multiplying by LCD, 6 ----- eq (i)
4x - 5y = 86 ----- Multiplying by LCD, 20 ------ eq (ii)
3x - 2y = 5 ------ eq (i)
4x - 5y = 86 ----- eq (ii)
- 15x + 10y = - 25 ----- Multiplying eq (i) by - 5 ------ eq (iii)
8x - 10y = 172 ----- Multiplying eq (ii) by 2 ------ eq (iv)
- 7x = 147 ----- Adding eqs (iv) & (iii)
x = , or
- 63 - 2y = 5 ----- Substituting - 21 for x in eq (i)
- 2y = 5 + 63
- 2y = 68
y = , or
You should be able to do your own check!!
