Find two numbers whose sum is 92, if the first is 4 more than 7 times the second

Your equation is (7x+4) + x = 92. combine like terms, getting 8x + 4 = 92. then, subtract by four on each side, getting 8x = 88. to get the x alone, you have to divide by 8 on both sides, therefore, x = 11. then, plug 11 into 7x+4 to get your second number. 7x11 = 77, 77+4 = 81. 81 + 11 = 92.

It’s 24.6 after you round to the nearest tenths the answer should be 25.0
