Question

(i) x, if 4x + 3y = 23 and y=5
Ans fast

Answer 1

Answer:

Step-by-step explanation:

4x + 3y =23. (Y=5)

4x + 3 × 5=23

4x + 15=23

4x= 23-15

4x =8

x = 8÷ 4

x = 2

Answer 2

Given:

• 4x + 3y = 23
• y = 5

To Find:

• The value of x.

Solution:

We already have an equation and y value with us,

Let  4x + 3y = 23 → (equation 1)

On substituting the value of y in equation 1 we get,

⇒ 4x + 3*5 = 23

⇒ 4x+15 = 23

⇒ 4x = 23-15

⇒ 4x = 8

⇒ x = 8/4

⇒ x = 2

∴ The value of x = 2
