Solve the system using substitution.
2x - 5y = 26
X - 5y = 3

(x, y) = (23, 4)

Step-by-step explanation:

2x - 5y = 26

x - 5y = 3 $\Rightarrow$ x = 3+5y

substituting the value of x ( second equation) into the first equation, we get, 2(3+5y) - 5y = 26. Simplifing, we get,

6+10y - 5y =26

5y = 20

y = 4

So, x = 3+5*4 = 3+20 = 23

Step-by-step explanation:

you can add 5y to both sides of the second equation:

Then, substitute:

use the distributive property on the left side:

subtract 6 from both sides

divide both sides by 5

Substitute into original equation

300

step-by-step explanation:

28-600w < 300

28-600w > 300

600-28w < 300

600-28w > 300
