It's x = 4 and y = 2.

3(4) + 4(2) + 6 = 12 + 8 + 6 = 26

Answer:

Option (a) is correct.

x = 4, y = 2 make the equation 3x + 4y + 6 = 26 true

Explanation:

Given : Equation 3x + 4y + 6 = 26

We have to find the values for x and y make the given equation 3x + 4y + 6 = 26 true and choose the correct option from the given options.

We will check each option one by one.

Consider

a) x = 4 , y = 2

Substitute in left side of given equation 3x + 4y + 6 = 26

LHS = 3x + 4y + 6 = 3(4) + 4(2) + 6 = 12 + 8 + 6 = 26 = RHS

b) x = 5 , y = 6

Substitute in left side of given equation 3x + 4y + 6 = 26

LHS = 3x + 4y + 6 = 3(5) + 4(6) + 6 = 15 + 24 + 6 = 45 ≠ RHS

c) x = 4 , y = 3

Substitute in left side of given equation 3x + 4y + 6 = 26

LHS = 3x + 4y + 6 = 3(4) + 4(3) + 6 = 12 + 12 + 6 = 30 ≠ RHS

d) x = 3 , y = 5

Substitute in left side of given equation 3x + 4y + 6 = 26

LHS = 3x + 4y + 6 = 3(3) + 4(5) + 6 = 9 + 20 + 6 = 35 ≠ RHS

Thus, Only Option (a) satisfies.

So, x = 4, y = 2 make the equation 3x + 4y + 6 = 26 true
