Question

Find the value of x and y, if (2x - 3, 4y - 1) = (5, 7).

Answer 1

Answer:

Anytime we have two true equations, we can add or subtract them to create another true equation.

Step-by-step explanation:

For example, here are two very basic true equations:

2 = 22=22, equals, 2

5 = 55=55, equals, 5

We can add these equations together to create another true equation:

2+    57=2=5=7

Or we can subtract these equations to create another true equation:

2−    5−3=2=5=−3

Here's another example with more complicated equations:

2x+3+    4x+16x+4=7=9=16
