The given expression is
And we have to find the equivalent expression.
First we simplify the given expression by distributing 3 on 2x-5. That is
Now we combine the like terms, that is
And that's the simplified expression. And hence the correct option is C .
Answer:
see explanation
Step-by-step explanation:
Given the 2 equations
3x - 6y = - 12 → (1)
x - 2y = 10 → (2)
Rearrange (2) expressing x in terms of y by adding 2y to both sides
x = 10 + 2y
Substitute x = 10 + 2y into (1)
3(10 + 2y) - 6y = - 12 ← distribute left side
30 + 6y - 6y = - 12 ( subtract 30 from both sides )
0 + 6y - 6y = - 12 - 30 , that is
0 = - 42 ← not possible
This indicates that the system of equations has no solution.
The 2 lines must therefore be parallel with no intersection
