A 2-digit number with x units and 7 less units than tens.
Hatshy [7]
Each two digit number has two numbers (duh!). Let's allow the tens digit to be x and the units digit to be y. Tens digit is 3 less than the units digit: x = y-3 Original number is 6 more than 4 times the sum of the digits: 10x+y-6 = 4x + 4y This gives us simultaneous equations!First let's clear the mess: 1. x= y-32. 6x-3y=6 Substitute 1 into 2: 6(y-3) -3y =66y - 18 - 3y = 6
 3y = 24y = 8 Our units digit is 8 Substitute y= 8 into 1. x = y - 3x = 5 Our tens digit is 5 Therefore, our number is 58

Solve for k, m = 3kx/7 - 9
kap26 [50]

Answer:

(7m + 63)/3x = k

Step-by-step explanation:

<em>m=3kx/7 - 9</em>

<u><em>add 9 to both sides:</em></u>

m+ 9 = 3kx/7

<u><em>multiply both sides by 7:</em></u>

7(m+9) = 3kx

<u><em>distribute the 7:</em></u>

7m+63 = 3kx

<u><em>divide both sides by 3x:</em></u>

<u>(7m + 63)/3x = k</u>

3(x+4)=3(x)+3(4) distributive property
jok3333 [9.3K]

Answer:

3(x + 4) = 3(x) + 3(4)
3(x + 4) = 3x + 12
3x + 12 = 3x + 12

Subtract 12 from both sides
3x + 12 - 12 = 3x + 12 - 12

3x = 3x
3x - 3x = 3x - 3x
= 0
