Question

Given that 5 x − 3 y = 32 Find y when x = 4

Answer 1

y = 16/3 or 5.333333...

Explanation:

5x - 3y = 4

→ Substitute the value of x = 4 into the expression

(5 × 4) - 3y = 4 ⇔ 20 - 3y = 4

20 - 3y = 4

→ Minus 20 from both sides to isolate -3y

-3y = -16

→ Divide both sides by 3 to isolate y

y = 16/3 or 5.333333...

Answer 2

y=-4

Solution,

X=4

Now,

`5x - 3y = 32 \\ or \: 5 * x - 3y = 32 \\ or \: 5 * 4 - 3y = 32 \\ or \: 20 - 3y = 32 \\ or \: - 3y = 32 - 20 \\ or \: - 3y = 12 \\ or \: y = - (12)/( 3) \\ y = - 4`

Hope this helps...

Good luck on your assignment..
