Question

If 7x+3y=9 is a true equation, what would be the value of 7x+3y−10?

Answer 1

• -1

Explanation:

Given

• 7x + 3y = 9

We need to evaluate :

• 7x + 3y - 10

We already know the value of 7x + 3y, so substitute its value in the given equation and solve.

• 7x + 3y - 10
• 9 - 10
• -1

Answer 2

-1

Explanation:

7x+3y = 9

7x+3y is 9 so it becomes -
