The number is 6 because five times 6 is 30, and 30 minus 2 is 28. You could also solve this backwards in the future and take 28 plus 2 and then divide that number by 5 (opposite of subtracting 2 is adding two, opposite of multiplying by five is dividing by 5).

5x-2=28 (writing it this way might also help, because now you just have to solve for x)

2 less than (-2) 5 times a number (5x) is (=) 28 (28)
-2+5x=28
add 2 to both sides
5x=30
divide both sides by 5
x=6

the number is 6

Icated (Q#1-4).<br> 2. Solve by substitution; x+3y + 4)<br> 3x - 5y = 8<br> 3 (3x+4)<br> aytla

Answer:

See explanation

Step-by-step explanation:

Assuming your system is:

$x + 3y = 4$

$3x - 5y = 8$

Then make x the subject in the first equation to get:

$x = 4 - 3y$

Put this equation into the second equation to get:

$3(4 - 3y) - 5y = 8$

$12 - 9y - 5y = 8$

$- 9y - 5y = 8 - 12$

$-14y = - 4$

$y = \frac{ - 4}{ - 14} = \frac{2}{7}$

This means that:

$x = 4 - 3 \times \frac{2}{7}$

$x = 4 - \frac{6}{7} = \frac{22}{7}$
