Answer:

The value of 5x+2y-6 is 20

Step-by-step explanation:

The problem is substitution into equation.

x and y are called unknown variables

Since we have been given values of x and y, we replace them with the values given to solve the expression.

5x means 5 times x

2y means 2 times y

Step 1. Substitute the given values of x and y

When x = 4 and y = 3

5x+2y-6 = 5(4) + 2(3) - 6 = 20 + 6 - 6

= 26 - 6 = 20
