Answer:
15a^7b^4
Step-by-step explanation:
add exponents that have the same base
multiply the 5 and 3 together to get fifteen
add 2 and 5 to get a to the power of 7
add 3 and 1 (the b is to the power of 1) to get b to the power of 4
X+y=?
Would be the equation i am pretty sure
The given equations are;
2x-y=8......(i)
3x+y=17......(ii)
Adding equation (i) and (ii), we get
5x=25 ( as +y and -y is canceled out during addition)
Hence x=5
Now
Substituting the value of x in equation (i)
2x5-y=8
10-y=8
Hence y=2
Step-by-step explanation:
3
