Question

Suppose x=2y-7. What is x if y=5

Answer 1

x=3

Explanation:

x=2y-7 and y=5

x=2(5) - 7

multiply 5 by 2

x=10 - 7

substract 10 from 7

x=3

Answer 2

• x=3.

Explanation:

Given equation:

• x=2y-7

Given variables:

• y=5
• x=?

Simplify, then solve:

• x=2y-7
• = x = (2 * 5) - 7
• = x = 10 - 7
• = 3
• x = 3.
