You have to make sure that whatever you do to one side, you also do to the other.
2x + 37 = 8x + 7
2x + 37 - 2x = 8x + 7 - 2x
37 = 6x + 7
37 - 7 = 6x + 7 - 7
30 = 6x
30 / 6 = 6x / 6
5 = x
x = 5
Hope this helps! :)
Answer:
60 grams
Step-by-step explanation:
For these type of questions, we can equate the ratio with the actual amounts. We will let the quantity to find be an unknown variable, such as x. Then we equate the ratios, cross multiply, and use algebra to solve.
Let grams of zinc be "x", so we can write the ratios and actual amounts as:
Then we cross multiply and solve for x, what we want to find out. Shown below:
There are 60 grams of zinc.
