First, move all terms containing a to the left, all other terms to the right.
Add '2b' to each side of the equation.4a + -2b + 2b = 16 + 2b
Combine like terms: -2b + 2b = 04a + 0 = 16 + 2b4a = 16 + 2b
Divide each side by '4'.a = 4 + 0.5b
Answer
= 4 + 0.5b
Happy studying ^-^
The egation is 58/0.79=73
the cocoa ways 73% of the grams and 73% of 58 is 42 so the cocoa weighs 42 grams in total
58=7/4x
Multiply both sides by 4 so the fraction cancels out:
232=7x
Divide both sides by 7:
x=33.14 (rounded)
Hope this helps :)
