4 cups of pecans = 5 cups of walnuts
x cups of pecans = 8 cups of walnuts
CROSS MULTIPLY
4*8 =5x
5x = 32
DIVIDE BOTH SIDES BY 5
5x/5 = 32/5
x=6.4
Therefore, 6.4 cups of pecans would be added to 8 cups of walnuts
1. <span>4x=7(x-3) -----> Start with the given.
2. </span><span>4x=7x-21 -----> Distribute 7 by multiplying it to the individual terms inside the parenthesis. 7(x) - 7(3) = 7x -21
3. </span><span>-3x=-21 ------> From step 2, combine like terms by transposing. The equation becomes 4x - 7x = -21. Simplifying, it becomes -3x = -21
4. x = 7 -----> Divide both sides by -3, you get the value o x.
Hope this helps :)</span>
