Answer:
6
Step-by-step explanation:
Multiply 7x+3 by 2. When you get 14x+6, set equal to 90 and solve for x.
If you're doing it mentally, you should find a common factor between the nominator and denominator that also multiplies to make 100.
So here,
Divide top and bottom by 6.
That gives you: 3/4
3/4 is 75%
3 x 25 = 75
52 /(-4)= -13 so the answer is 52
