Icated (Q#1-4).<br> 2. Solve by substitution; x+3y + 4)<br> 3x - 5y = 8<br> 3 (3x+4)<br> aytla
puteri [66]

Answer:

See explanation

Step-by-step explanation:

Assuming your system is:

x + 3y = 4

3x - 5y = 8

Then make x the subject in the first equation to get:

x = 4 - 3y

Put this equation into the second equation to get:

3(4 - 3y) - 5y = 8

12 - 9y - 5y = 8

- 9y - 5y = 8 - 12

-14y =  - 4

y =   \frac{ - 4}{ - 14}  =  \frac{2}{7}

This means that:

x = 4 - 3 \times  \frac{2}{7}

x = 4 -  \frac{6}{7}  =  \frac{22}{7}
