Question

a )find the equation for twice added to 50 gives 72

b) five times a number taken away from 12 gives - 22​

Answer 1

Answer:

a=6 b=2

Step-by-step explanation:

a. let the no taken be x

2x+ 50= 72

2 x=72-50

2 x= 12

x=6

b. let the no be y

12-(-5x)=22

12+5x=22

5x=22-12

5x=10

x=2
