Question

solve for x y=7x+5
y = 9x+4

Answer 1

Answer:

x = 1/2

Step-by-step explanation:

y = 7x+5

y = 9x+4

7x+5 = 9x+4

1=2x

x = 1/2 = 0.5

Answer 2

Answer:

1. $x = - \frac{5}{7}$

2. $x = - \frac{4}{9}$

Step-by-step explanation:

$y = 7x + 5 \\ 0 = 7x + 5 \\ - 7x = 5$

$\boxed{Answer:{\boxed{\green{x = - \frac{5}{7}}}}}$

$y = 9x + 4 \\ 0 = 9 x + 4 \\ - 9x = 4$

$\boxed{Answer:{\boxed{\green{x = - \frac{4}{9} }}}}$
