Question

Solve the system by the elimination method.
6x-9y=7
-4x+6y=10
a. An infinite number of solutions
b. (0, 5)
c. (5/6,5/2)
d. No solution
e. None of the above

Answer 1

try to have the coeficients of x or y equal

Answer 2

for example multiply the first eq by 4 and the second by 6
what do you get?

Answer 3

Oh, OK thanks

Answer 4

@Kalisa @helder_edwin
d.No Solution
as\[\frac{a_1}{a_2}=\frac{b_1}{b_2}\neq \frac{c_1}{c_2}\]

Answer 5

d. No Solution\[\left\{y=\frac{2 x}{3}-\frac{7}{9},y=\frac{2 x}{3}+\frac{5}{3}\right\} \]Both lines have the same slope, 2/3, and will never cross when plotted.
