Question

Solve the equations and check if you got the correct solution.
A. 6X+ 5 = 47
B. 18 = 8y-6​

Answer 1

Step-by-step explanation:

You can subtract the second equation from the first equation to eliminate y:

7x + y = 25 – 6x + y = 23: 7x – 6x = x; y – y = 0; 25 – 23 = 2

x = 2

You could also solve one equation for y and substitute that value in for y in the other equation:

6x + y = 23 → y = 23 – 6x.

7x + y = 25 → 7x + (23 – 6x) = 25 → x + 23 = 25 → x

Answer 2

Answer:

1.)

$6x + 5 = 47$

$6x = 47 - 5$

$6x = 42$

$x = \frac{42}{6}$

$x = 6$
