Multiply across for example 3/20= x/100
3*100=300
x*20=20x
then divide by 20 on each side
300/20=15
15=x
Answer:
a = (15-11b)/7
Step-by-step explanation:
19a + 11b = 12a + 15
Subtract 12a from each side
19a-12a + 11b = 12a-12a + 15
7a +11b = 15
Subtract 11b from each side
7a+11b-11b = 15 -11b
7a = 15-11b
Divide by 7
7a/7 = (15-11b)/7
a = (15-11b)/7
Answer:
15 units
Step-by-step explanation:
